Some of my pages seem to have gone missing


I had to restore my site using one of my backups (both wp install and mysql file) and now some of my pages seem to have gone missing. They're the ones created by the plugin TT Marketpress Frontend Admin, you can access the plugin settings and check the pages it generates here:

I remember Tyler Postle mentioning in a chat session a wp admin area I could go to to see a full list with all the pages accross my network -no, it isn't wp admin > pages. But even if these missing pages are displayed there, oddly they aren't being displayed in my list of pages at wp admin > pages anymore, and they used to be.
