I have a SharePoint Project Tasks file that is synced up with a local MS Project file. I saved a template of this list as a backup and wanted to restore it. Ive uploaded the .stp to my List Templates folder but it is not showing when I go to "Add an App". Looking into it a bit further, it seems that this type of list template is hidden by default, so even though it is uploaded correctly I am unable to add it in like I would with any regular custom list template.
So, is there anyway to make this type of template available so I can then add it to my site?
