Its works too strange

[JellyTyan]

When I edit the top part, it can simply stop editing. I delete the top part, change the name, texts and nothing happens. I try to import from another file and the same thing. I am not even talking about export to pdf, which also works strangely.

Same Problem, I though I was just me.

@Licomix would be helpful if you describe concrete steps to reproduce the issue, share the console logs and your current version.
