Cucina pasta machine won't grip on spaghetti side but does on linguini side

Everywhere I have found online to fix this problem talks about altering the dough but that's not the issue. My dough is fine and grips well on all the other rollers of my Cucina machine. It's been cleaned and has no debris or anything. It just will not grab the dough to cut spaghetti. I've tried different thicknesses or even pushing it in, and it doesn't work. I've tried turning by hand and using the motor. None of that works.

Does anyone have any suggestions as to how to fix this?

Thanks
