Macintosh 10.14.2

Finale 26.0.1

Finale will not copy materials from 1 location to another in the file. Needing the same 2 bars later on in he piece, I tried using the selection tool, the time signature tool and even dragging the 2 bars and the destination measures stay blank. Also, when copying lyrics to other locations, they come out as gibberish and the font changes in the lyrics window. When I change it back, it shows "0" for the size. When I change it to a number, it goes back to"0."
