Mpc key 61 won’t loop properly

I’ll loop a 4 measure beat with some 4 note chords on the click of the metronome, and it sounds great through my headphones while I’m playing, but when I play it back each note has drastically different dynamics and each note is even off beat from one another. I’ve turned off timing correction messed with the tempo turned it off and back on but I can’t get it to work properly. I don’t have this issue if I plug the keyboard into my actual looper pedal every thing loops how I play it only when using the loop function in the mpc key 61. Dose anyone else have this problem or is it a bug?
