I'm having a weird issue after I set my media share to Secure. I reconfigured Windows Credential Manager, and gained access to the share, however the issue is that one of the folders therein will not allow me to make to delete any sub folders. It goes Media\tvshows\[tvshow]\[show file] I can make and delete folders at any level except for the patent tv shows folder, I can edit in the Media share, and in the [tvshow] folder, but not in-between. I have set the share back to public, and the problem is persisting, any help would be much appreciated.

Tools - New Permissions on only that share.

That worked a treat, I misunderstood the guide at the top of that page, thanks!
