Duplicated styles in repeater after Copy Element Design (from this breakpoint)

In Wix STUDIO I have an ongoing issue where I created a Repeating Slideshow with 6 slides. It worked fine until I clicked on an element and went to the submenu “Copy Element Design (from this breakpoint)”. Then an icon/cursor came up and I tried to close it but I must have selected something. Ever since then whatever element gets a change in the slider (text, buttons, colors) it applies it to all the slides, instead of only that slide where the change is made.

Is there a way to disable the Copy Element Design (from this breakpoint) that I believe I activated?

I have tried restoring to an old site version, deleting and creating a new Repeating Slideshow, changing browsers, logging out of Wix, and closing the browser. Nothing has worked to this point. Help!
