APM - Hometab appears, despite checkbox cleared in portal access.

Quick update for the community. The answer has been discovered by F5 Support, this wasn't a bug but an issue with the resource items and the back end servers.

Say the resource items were as follows: https://10.10.10.1 - Hometab Disabled, SSO added.

This initially works, when a certain link was clicked on the backend server it used an absolute url which changed the requested resource from 10.10.10.1 to an internal DNS (or other IP).

This then meant, as there is only one resource item, that there was no resource item to match the newly requested resource and disable hometab.

So back end application, technically at fault, but I found it a little tricky to spot.
