Your picture didn't come through, but see if you have more than one file location for your document templates.
Under the firt dropdown that says: Show folders for: select Document Templates
If you have more than one folder shown under Folders: it could be creating your duplicates. If so, delete one of the file paths. You can change your stored locations here as well.
Awesome. That did it. I had created a custom location and kept the default Solidworks Location as well.
I've been using Solidwors for a long time now and have never seen this issue.
This is my first time posting a question to any blog ever. Thank you for makeing it a good experiance!
