Measure length incorrect
The attached file came from the PDF tool here. There are errors, and so I am trying to correct them, but being quite new to MuseScore I am struggling to understand what I am seeing.
The first thing I did was add the 4/2 time signature, and added a double whole note rest into the first measure. However, it seems to think that 9 1/2 quarter notes are needed. Why is that, and how do I correct it?
