I added some slurs here in Galley view:
Switching to Page view makes them disappear:
How do I fix this?
Are you sure you’re looking at the same instrument?
It’s not only those slurs, a note is missing on the first beat of measure #99 too, And the hairpin, and the ff at bar 97, and the trill …
I am sure I am looking at the same instrument. In Page View, the staff is shared between the bass trombone and the tuba, which explains the higher note in m.99. The hairpin and the ff also disappeared from the condensing.
Ah, sorry, didn’t read the topic title, just the body.
You may be able to recover the slurs by setting a manual condensing change (that does nothing) at the start of bar 99, though it may not respect the slur into that bar.
Condensing has its quirks. If you could upload the score someone may be able to help.
Here is the file. The issue is at m.97.

There is a Condensing Change in bar 27 for Tbn. 3 / Tuba to force both instruments to stems up.
Change that to Reset condensing.
You could insert another condensing change with stems up/down in bar 97.
And you can flip the trill in Engrave Mode.
