Latency on loop playback

Hi! I use MuseScore to write down exercises for my drum students and it's wonderful but when I want to play along with it and loop just 1 bar it seems that the repeating bar is always coming with a little latency, I put the metronome as well and I can still hear it, I checked with an external metronome and after a few bars both metronomes are getting far away, so that means that the loop is not accurate.
If I copy the same bar for like 50 times there's no latency because it just playing one bar after the other but if I want to loop 1 bar is quite annoying. Is there anything I can do?
Please let me know!

Alex 😊
