Every Minecraft world says (with touchscreen mode enabled): Don't forget to backup this world! (In the new worlds, too!)

Please do not mark unreleased versions as affected.
You don't have access to them yet.

So... Delete this bug? I Can't fix it!

Please switch the language to English and reattach the screenshot.

Oh, I'm sorry for late, but it says "Don't forget to save this world before start the snapshot"...

But still the error, a minute
