Problems when editing text style

Editing text style:
very confusing! A lot of things are here to be edited, but the larger part doesnt work at all, or only after restarting the programm. To name a few:
- instrumentnames (long & short): changing properties has no effect
- rehearsalmark, idem
- page numbers do work, great!!
- changing lyricsfont results in a mixture of old and new fonts, very strange, has something to do with the different syllables.
- i noticed that somehow, for no apparent reason the first syllable of (some) words tend to turn into a larger size. Only correctable by typing the lyrics again. Very annoying.
