Resting cable length discrepancy

Hey everyone! I got 2 Voltras about a month ago and have absolutely loved them. They have unlocked so many things I can do in my garage gym.

That said I just noticed this morning that one of my voltras has a resting cable length a half inch longer than the other which is kinda annoying. I’ve tried rolling back the cable several times but it stays the same. I’ve always been super careful not to leave attachments hanging there when not in use, and I was curious if this has happened to anyone else? And if there is anything I can do to get them evened out.
