Inactive user on "resources report" - how to delete him from the list?

Good Afternoon,

I generated resources report and I can see that in all passwords one user have read permission but that user was blocked and he shouldn't be there.

I checked user access snapshot and teoretitcly user have that access but when I tried to delete him from resourecs and group of resources it shows me that he don't have access (so can't delete him).

Can someone help me please to find how to delete him from resources?
