Hi and welcome to COOK @dangs83613@mypacks.net,
I've never experienced this but here are a couple of things to check...
When you added the field to the layout, did you drag the
users table element instead of one of the fields, for example, username?
If so, remove the field from the layout and and re-add it by navigating to the fields list, down to users (table) and click the '+' sign to access the username, email address or name according to how you want the creator to be displayed.
If this is not the issue, please could you post your CONFIG details as per this topic:

many thanks,
Gez
