Hi 2MuchStuff,
We've encountered an issue in the Custom Item Specifics portion of the lister page for some categories. We have now identified the cause of the issue and are actively working on a fix. We expect to have this resolved today so I'll be sure to post again here, with an update once I get confirmation it has been fixed.
We're terribly sorry for the inconvenience this has caused and appreciate your patience as we work to fix this.
Sincerely,
Natasha
