I was working on this sheet in musescore but I got up to the second bar in this image and it seems to be the wrong length for the time signature. If I try to add quarter notes to it I can only fit in 3 and if I attempt to delete the bar it just messes up the next one. What would be causing this and how can I fix it?
The version of musescore used is
OS: Linux 5.1.16-300.fc30.x86_64, Arch.: x86_64, MuseScore version (64-bit): 3.2.3., revision: github-musescore-musescore-d2d863f
