How to break inheritance between page and it's copy?

Hello! I’m just a beginner in webflow, I need to make a portfolio, but I stumbled upon a problem that I can’t solve.

I made a page with buttons and then made a copy of that page. On the copy, I want another button to look pressed, not the one on the first page, but apparently the style is inherited from the previous page and when I change the button on the second one, the button on the first one also changes. How can you unlink styles between these pages? Renaming button elements does not work either.

By adding a combo class or removing and replacing one. Learn more about how to use classes in the WF University.
