Ok, I’ve encountered my very first Sketch bug:

I saved my file with a visible layout and I can’t switch it off now. When I toggle it there is a new layout with default settings coming up and the old one remains to be visible. I reverted to older version but that layout reseted to default somehow and when I enter layout setting guess what?.. Second layout! lol is it just my luck or my stupidity or is this thing really this buggy, please, I don’t want to go back to Illustrator.
