@jdruding Hey ! I'm really sorry, but now with a second kid I use my precious little free time playing; and work has ramped up so I don't have much time there anymore. But I'll make sure to check it when I ever get back to it.

I found myself in the same situation when I installed the Retropie Manager. Told me I had invalid BIOS files and also rom titles I tried to transfer to my pi. I already was transferring through ssh, but thought I would try the manager out. Boy was I mistaken..lol.
I had the same problem, but it was inconsistent. I wanted to add Rugrider to the Commodore 64 emulator. I was dragging and dropping and everything but no luck. I was able to drag and drop plenty of other games though.
The file extension was .D64 and was failing. I changed it to .d64 and it succeeded. Seems that the file type is case sensitive for this instance at least.
Best of luck!
Maybe worth noting for folks who may not be aware - Linux is case sensitive, unlike Windows.
I uncommented it and set the rights as you advised:
