Closing a project in RoboHelp 10 causes rhtemplate.apj to get checked out

For some reason, when I click "close project" in RH10, the rhtemplate.apj always gets checked out and remains checked out. Everything else will get checked in except for this template file, for all projects I work with. This only happens if I make a change to the project.

I can go to the Robosource 3 explorer and check in this file there, but it causes extra work for me and it shouldn't be doing this.

Has anyone else experienced this issue and found a solution?
