Open Overlay Manual Prototyping Issue

Hello. Newbie here. I’ve searched and tried solutions in the community and can’t seem to resolve this issue I’ve been stuck on for a while:
I am using the Open Overlay - Manual for Frame 11, “11. Delivery Details” on a bunch of frames. I’ve turned all my overlays into frames and made sure my starting points were frames as well. They’re still not working in the Prototype. I also tried switching some to Swap Overlay without resolution.
Any ideas or suggestions? Thanks so much in advance!
