I deleted Subpage two (which came with the template) a while ago and it doesn't show in design studio or power pages management.
I've recently set up authentication and can see that Subpage two is still showing in the portal.
I have just deleted Subpage one and Pages and those deletions behaved as expected i.e. they don't appear in design studio or the portal and are shown as inactive pages in power pages management.
This leaves me with Subpage two showing in the portal, which I can't see in either design studio or power pages management.
The screenshots below describe the above. Any suggestions how I can get rid of Subpage two?
