Why is vertical scrolling not available anymore as an overflow behavior?

[Andy_Mayer]

I’ve just noticed that I can no longer choose “Vertical scrolling” as an “Overflow behaviour” on any of the frames in my prototype. The option is displayed with a little exclamation mark to the left.

I have created a new empty frame, and get the same problem.

Previous frames with this option still scroll vertically, but I can’t edit the setting.

Help! I can no longer work on my project

Fixed thanks! I didn’t have any content overflowing the frame.
