Can't create "Open overlay"

Hi, what might be the problem, when I can’t create an “Open overlay” -connection from objects to frames in my prototype? For example “On click, Navigate to” works perfectly, but when I try to change it to “Open overlay” (or if I try to create one from scratch), the Destination field shows “None”.

Hello @Pia_West,
Were you able to get a resolution to this issue? I am also having the same problem with a design.
