Sample editor moving on its own

Hey there! This might be a somewhat newbie question. I purchased an OP-1 a few weeks ago and I love it, but whenever I sample something and go to the sample editing screen, sometimes the blue parameter will move on its own. This is pretty frustrating, especially when I’m trying to resample something starting from the very beginning of the sample. Any help would be much appreciated!

Check that the LFO is off.

Check lfo and master effect on the mixer

This was driving me nuts. So simple. Thanks!
