@_Stevie_: I tried to recreate the issue and having a file named 'Die Fallers.RPP' shows up fine here. So I'm not exactly sure yet, why it's not shown in your case.
But can you please check the following:
- Does pressing the [R] Refresh button in the Project Template tab make any difference?
- Are there perhaps a couple of blank spaces in the Filter input field (which might filter out the list entry)?
