MS 4.4.2 - changes affecting scores since MS 4.2.1

In the attached score which I established on MS 4.2.1, I had problems with slurs not being visible in parts although they were in the score. In some cases, they were not visible in the score as well.

I’ve just downloaded MS 4.4.2 and opened a copy of the score in question, see attachment. Now, some slurs are missing again and in both the score and in the part. See for example Harp 1 in measures 4, 8, 12, etc. I thought this was solved by now or am I wrong?

In addition, the page formatting is changed such that again as an example, Harp 1 page 4 only contains 1 staff. Has also this been changed since MS 4.2.1?

Maybe, there are more issues but I’ve only briefly checked for Harp 1 so far.
