"Save" and "Save As" behaving exactly the same

Using the latest beta 4.22.1.110. Clicking "save" brings up a window instead of just saving the scene immediately. Only started happening after I cleared out my appdata folder and let Daz rebuild it to fix some other bugs.

Enter something for Author name in Edit>Preferences (Daz Studio>Preferences on a Mac) and scenes created after that will save without prompting - DS won't silently overwrite files where the author noted in the file doesn't match the author set in DS in order to avoid accidentally ovewriting files from products (which would then require a reinstall to get back to the original, and also leave the user-modifications vulnerable to overwriting by a product update).
Thanks, that fixed it.
