Edits on tablet view automatically changes the desktop view


My question is after finishing my portfolio for the desktop view and move to tablet view,
After editing some elements on the tablet view like change font sizes or remove some images,
I found when go back to the desktop view that those elements have changed also, and I don’t want that and I don’t know if it’s a bug or something, so, please advice!
