Adjusting breakpoints changes them everywhere?

I’ve changed my website about 20 times trying to get my overrides on breakpoints to work. No i’m not an html professional. I know the adjustments cascade up past 1440x and down past tablet. When I make adjustments on tablet it changes my website everywhere as well. Same goes for adjustments on large desktop. All I want is to correctly override these changes so they stay on their specific breakpoints. I also don’t have amazing webflow vocabulary so this may not make sense. Feel free to ask clarifying questions. I’ve been slowly losing my mind.
