measure numbers are not updated on subsequent systems after adding offset

OS: Windows 10 (10.0)
Arch.: x86_64
MuseScore version (64-bit): 3.0.2.5315
revision: a8b90a8

1) Create a new MuseScore file
2) Create some notes with fingering for more than one system
3) Under Format > Style... > Bar Numbers: Set "Every system"
4) Change first bar's "Add to bar number:" (Under "Bar properties") to any other number

Results:
A) Fingering of the next system's first bar disappears.
B) The bar numbers of the following systems are not updated (only that one which properties were changed gets a new number).

A provisional solution: To see everything like it really is you just have to save the file. It's no big deal to do that every time, but it's a little annoying.

I'm sorry for my English.
