only enters rests, no notes

Hello All
I am brand new to MuseScore. I am trying to create a simple rhythm for kindergarteners using body percussion (hand clap 1 and hand clap 2) but it only seems to be entering rests, no notes. Is my program glitching or is it user error? My money is on user error lol. I have looked through the manual and have tried using 4 and 5 followed by 0 but it only enters rests. The rest is not highlighted in the menu when I am trying to enter the notes. When I hover I see a note, but then it enters a rest. Any help would be appreciated. Thank you!
