Clarification/regulations on verbiage & use of badges

Found this little oddity on the marketplace today and wondered if there are regulations on what you can/can’t use in your images and postings. In particular, it looks like the seller is using the phrase “Pro” as a badge (similar to Steam badges) to highlight their product. This seems misleading as it insinuates Epic has determined and given certain sellers statuses like "Pro. Can someone shed light on whether this is permissible or should be removed?
