New to this, so maybe missing something obvious. I just converted a pdf to musescore, and I'm trying to fix some conversion errors involving rhythm. Several measures have added extra beats (for example in a 2/4 time signature, I have measures with 3 or 4 beats) -- which happened when a dotted eighth and sixteenth was converted to a dotted quarter and eighth. For the life of me I can't figure out how to correct this in a way that changes the number of beats per measure. I'll change the individual note rhythms, but then rests will automatically get added to keep the total (wrong) number of beats in the measure, and I cannot delete them. I hope this makes sense!
