Why do my page change over night?

Every day i connect to wix, and every day i need to re-do the whole design of my pages, my boxes sliding up and down until they collapse into one another and become unreadable, my pictures overlapping on the text.
Also why is my grid disapearing partialy every days? i realized a grid of 50/50pxl and every days half the grid disapear making it even longer to re-clic and drag box by box the mess that unfold for no reasons…

Hey!

You would be better suited going through Wix Support about this issue as it is not a code issue:
