I’ve put a lot of screens into Figma to create a user flow of designs - but when I’ve just gone back to do more, it’s only showing the title of the link rather than the screen itself? Any ideas why it’s stopped showing the screen?

Hi
Looking forward to your reply!
It won’t let me attach a screen recording but I have screenshot the stages of what I’ve been doing. It’s worked before multiple times, just seems to have stopped now?
