It seems to be only one SSID that this happens for. When I search for clients I get results from controllers that are no longer in PI. They were removed back in August from the device center and no longer show up there. The client data is showing a last refresh date as August as well. I see current data as well but still shows old client data. I know I can click remove on every single client but the client numbers are not small and this would take lots of time as I dont see a way to select multiple clients.
Other SSID's that are in PI do not show this old data. They are current. Background tasks that run show no issues. They are running successful and as expected.
Before I open a TAC case just thought I would check and see if anyone has any ideas.
