Are you talking about submitting local changes? You'd just need to update the beatmap the same way you submitted it for the difficulties you want to update (save then Ctrl+shift+u or file > update beatmap!).
when changing the cymbals (i assume you're talking about the hit-normals) changes don't happen across difficulties so make sure they're the same on each difficulty (you can use ctrl+shift+a to see if ai-mod is pleased with your timings across difficulties)
