Hi! Could you provide some images to demonstrate what the issue is - there could be a myriad of different issues that you could be running into, but without providing an example relevant to your site its very difficult to work out!
What I understand of your issue is that the items within the containers get clumped up on mobile view, and when you edit them for mobile view, the edits cascade upwards to desktop view also - for clarification does this mainly effect text & button elements, or does this issue relate to images/other media also?
Thanks,
Elliot
