Selective sharepoint List templates are not listing as Apps that can be used (Add an App). Any clues as to why this is so?
I am able to save other lists as templates and these do show up as available Apps. This particular list was created from SP2010 (we are now SP2013), and appears to have been created from a Task type list.
Update:
I have tried to update the TemplateID and the FeatureID in the stp file as per this site
However, this did not work.
