Interface goes wonky after sending a sample

Bought a rytm used not too long ago. Started sending sample over to the rtytm using c6. Every time I send a sample over, the fx light stops working and the pads colours start changing colour by themself or pulse or have a low light.

The only thing that seems to fix it is to do a factory reset. Has anybody else experienced this behaviour?

Cheers

Nope, sounds weird. Have you tried factory reset + reformatting. Also make sure the PSU is correct.
