unable to delete ip List, even when no Firewall Rules present

Hello
I want to delete the IP list
I also removed all the firewall rules
I went ahead and cleared all my Firewall Rules, but it seems Cloudflare still thinks I still have 2 filter that uses this List, which is not the case.

The Pop-Up is still there even though I have no Firewall Rules.
I even went as far as to check with the API, I made a request to check my filter list, and my account-wide filter list, but they’re both empty, and I also checked the List, it says that 1 filter is using it.
Could it be that the filter belongs to a domain that I have since removed?
please help
