Master page not appearing in Project Set-up or in New Topic
I am using RoboHelp 8.0.2 and working on a local drive.
My project and the template was imported from RoboHelp 6.
The master page is not appearing the Project Set-Up even though it's in use in the project:

It also does not appear when I create a New Topic, so for each new topic I then have to go to the directory and select it. (It appears in the project's directory.)

It's used by every topic in my project and if I try to create a new Master Page with the same name, I get a message that this Master Page already exists.
Any ideas?
Thanks,
Debbie
