I found this score, as you can see the first measure only has two 16th notes, and the next measure is larger than first.
I was trying to pass this score using MuseScore, but I had to insert a lot of silence to only have two 16ths (equivalent to one 8th).
Is my score fine? if not, How can I fix it?
EDIT:
Secondary click over the measure:
