Employee Supplier site inactivated but not go away ?

Hello folks ,

We are having some changes in our active supplier sites . we deactivated ( In Addresses tab ) Old ones and created the new supplier sites. However these old sites are not seen anymore in addresses and summary screens , I see them with blank data still under the OU in Invoice managment /Tax / and other tabs on supplier work bench . Please can someone suggest to have deleted altogether from all tabs ? or its because any due transaction pending with those Old sites ?? Appreciate the answers

Thanks and Regards
