Hairpin's text offset position resets after closing and reopening file

1) Insert a hairpin
2) Select it
3) Mark "Begin Text" on inspector
4) Write something in the respective field
5) Change Begin Text Offset (so it looks like attached PNG or anything else)
6) Save and close the file
7) Reopen it
8) Offset changes on the text are lost
9) Any other offset changes made in the hairpin itself keep intact as it should be (what potentially messes up things a bit)
