Can get user fields to show now in attachment metadata

I have the pro version installed and working to upload images to the media library correctly with user fields on a test site, but now when trying to get to work on a production site, the user fields doe not seem to be added to the attachment metadata data as was done on the test site. The images are being uploaded to the media library, but the user fields are not.

After searching the database and the log, I see that the user fields are in wfu_userdata table, but not in the attachment metadata. Also I found that at first, the box on the setting page was unchecked (If enabled and the uploaded files are added to Media Library then any user fields submitted together with the files will be shown in Media Library). So I checked the box and tried again, but still do not get the user fields in the attachment metadata.

Production site is using https, test site is not – is that a factor?

Any suggestions?
