Actually, I had entered a 7/8 time signature for several measures. I copy and pasted it and somehow that issue occurred.
Fixed it! In the Time Signature Panel it said 2+2+3 (I had several 7/8 time signatures in previous bars). Thank you!
I erase the extra note, but a rest shows up, and I need that bar to be 6/8. What are the possibilities that would explain this? Thanks.
