Layout Invalid, Choose Template to publish

Xibo 2.0.1

After checking out a Published layout, and trying to publish again I get the following error stating:

This layout is invalid and should not be scheduled. Please choose a template.

Any ideas what i am missing here.

The team and I were able to determine the cause of the issue, naming structure for the layout included " !! " exclamation signs, once renamed, the issue went away. Also, if you copy the layout, and rename it also worked.
