Corrupted score.

"Incomplete measure: Part score: Flute, measure 71, staff 1. Found: 13/8. Expected: 4/4." I have no music written in for the flute part in measure 71. I even tried selecting the measure and pressing delete, or making it a full measure of rest, but the issue wont go away. It wont let me save the score unless that error gets fixed, and i cant figure how to fix it. (the image I attached says tenor sax, it just changes instruments between that and flute) Please help :( thank you.
