Problem with Album/Joining Scores

MuseScore 2.03, Windows 10 PC
First things first: MuseScore 2.03 is great!

I recently finished entering Schumann's Dichterliebe song cycle into MuseScore (as 16 individual scores), and I thought it would be a good opportunity to learn how to "Join Scores" under the Album Manager feature. However, it's kicking my butt. Maybe operator error, or maybe there's a bug.
All the songs are for piano & voice. There are minor differences in the style settings, but all have the same spatium size.
There are 16 songs in the cycle; I've only attached the first 8 for convenience (plus the "joined" first six songs as "Test 2".
Short version- With difficulty, I'm only able to get the first 6 songs joined. No success getting the 7th added. MuseScore crashes.
Long version (FYI I've done many, many, variations on the below, but all end with the same result: MuseScore crashes, unable to get more than 6 songs joined.)

1. Open MuseScore, no scores are open.
2. File>Album; click New>change name from Untitled to Test 1. Do not Join Scores or Close yet.
3. Add Score> select Dichterliebe 1 & 2.
4. Join Scores> keep name of Test 1>save to desired folder> Test 1 mscz is created. Good so far.
5. Add Score> select Dichterliebe 3.
6. Join Scores> Keep same name, save to same folder, accept "Test 1 already exists, replace?">Yes.
7. Add Score> select Dichterliebe 4.
8. Join Scores> Keep same name, save to same folder, accept "Test 1 already exists, replace?">Yes.
9. Popup message appears: X Runtime Error! Program (musescore.exe) This application has requested the Runtime to terminate it in an unusual way.
10. Acknowledge the message, new popup message: MuseScore.exe has stopped working.
11. Restart MS>new popup message: The previous session quit unexpectedly. Restore?>Yes.
12. Open Test 1 in MuseScore, despite the crash, all 4 songs are in the joined score. Note that, since the Album Manager was never closed prior to the crash, the album "Test 1" was not created.
13. Close the Test 1 score.
14. File>Album; click New> create new album "Test 2".
15. Add Score> select Test 1.mscz.
16. Close the album manager and save Test 2 to the desired folder.
17. File>Album>the Album Manager opens with the Test 2 album already selected. (This is unexpected; Album Manager should have opened with no albums showing.)
18. Add Score> select Dichterliebe 5>Join Scores> save with same name to same folder, accept "Test 2 already exists, replace?">Yes.
19. Add Score> select Dichterliebe 6>Join Scores> save with same name to same folder, accept "Test 2 already exists, replace?">Yes.
20. Popup message identical step 9 above appears. MuseScore crashes.
21. Restart MuseScore, open Test 2.mscz, on review all 6 songs are in the joined score.
22. Close the score Test 2.
23. File>Album>the Album Manager opens with the Test 2 album already selected. (This is unexpected; Album Manager should have opened with no albums showing.)
24. Repeat the exact steps above & attempt to join Dichterliebe 7 to Test 2 (which has songs 1-6).Join Scores> save with same name to same folder, accept "Test 2 already exists, replace?">Yes.
25. NEW popup message appears: "MuseScore has stopped working".
26. All further attempts to join 7 to the first 6 in Test 2 cause MuseScore to crash with the error message of step 25.

For what it's worth, on my very first attempt to join the scores, I selected all 8 at the very beginning of the Join Scores process. MuseScore crashed (sorry, I didn't document those steps; wasn't expecting a crash and assumed operator error). So I tried again using only a few scores at a time, and had somewhat better luck, but still not getting the desired result. I've reviewed the on-line Handbook section on albums & joining, however it's very sparse and was not much help.

Thanks in advance for the help.
