Is this a bug,or am I doing something wrong?

I made a track template for Slate drums,saved it,everything was fine,no error messages.Then I decided to make a folder within the folder track for the cymbals and another folder for the room groups.The two folders are inside the drums folder but not each other.I saved the template & while it works fine,I get an error message when opening the template that occurs twice,I assume because of the two sub folders.After hitting ok (twice),everything works fine,but will this template cause problems because of the multiple folders in a master folder?If I remove those two extra folders & save it again I get no error message so it must be the folders causing it.Ive attached two jpegs one of the error message & one showing the track template.

Do you mind uploading the template to stashbox and post the link here?

This is very strange,after loading a few more times,Im no longer getting the error message.
