I'm attempting to make an internal pocket, where both edges from a cut into the fabric are turned inwards along a fold line but I keep experiencing an issue where the fabric that is being folded clips through the body and has a spiraling effect.
It happens to both edges, and always starts from the bottom
I can usually stabilize it but as soon as there's any major movement the issue occurs again

This is how my cut/ fold lines are setup:
How can I fix this, or what might be my best approach for preventing it?
