credit cleared in 2023 but still showing

I had a Makro store card that i settled with a company called credit solutions because they handed it over i settled the account in 2023 now it is suddenly popping up again because they sold it to nimble i have given nimble all the proof that i settled already but when i check i still owe them which is now messing up my credit score ,i have been fighting this for months now with no luck @ rcs please clear my name and pay nimble back the money they used to buy the debt
