I had changed it in both places... in the global settings and also on the conversion window that pops up when you do the actual conversion, I made sure they both matched.
For whatever reason it didn't hold, it is holding now, so I'm a happy camper.
Edit: Now that I think about it, trying various things I did check the box to include the metadata purposely on the window that comes up when you click Convert. I did a conversion, it turned out as it should with the metadata. Then did another conversion and unchecked that box... and that was the 3rd time that worked.
