I tested in 2E and it works. What ruleset? Keep in mind that it's built around 2E/5E for locking. Other systems might/might not work due to structure of their data.
I don't use MoreCore so can't say for certain... but that data is populated by the ruleset/extensions. If the record type doesn't exist then it won't show. I don't see a record_classes.xml in the campaign code section of MoreCore tho.
