Project Audio Files being dumped into Template Audio Folder?

Hi - In upgrading to 6.0.5 today I found out why my C drive was getting so full - for some reason all my project audio files from my last project created in 6.0.0 were winding up in the Template audio folder (i.e., in the Preferences folder in the C: drive).

I’m not sure why this would have happened - I thought I always start a new project by creating a new project folder.

Could the above observation (project audio files being placed in C: drive’s Cubase Template audio folder) have happened if I inadvertently opened and worked on a template for a while before renaming it to the project name?

I’m just trying to keep it from happening again.

Thanks much -
