I cannot select the time signature in either Engrave mode or Write mode in the 2nd ending. It is not needed. How can I hide or remove it?
It looks like an automatic restorative time signature. You can get rid of it by setting Notation Options > Repeats to Do Not Track. (Although then you’ll also lose the cautionary time sig at the end of the first ending.)
I admit that I’m having a little trouble reproducing this to verify, because I can’t see what’s happening in the previous systems. If the suggestion above doesn’t work for you, then please upload your project file so someone can take a look.
@asherber I tried your suggestion and behaved as you described. The helpful end of bar Time Signature marks disappeared, along with the incorrect one in the last bar. Hopefully a future release will provide more intelligence and/or options.
There are several options in Layout Options > Repeats
It would be nice to be able to have a “Hide” option here – and also to be able to change the display of any individual item in the Properties panel.
