Here is my suggestion.
How about adding the adventure's owner name under the Adventure so players can tell which is the LS and which is their adventure?
Yes, you should be able to tell the difference, but for new ls sellers, this might be confusing. Especially if they have 2 of the same adventures showing at the same time.
And adding the player's name would take 1 line under the adventure title.
Example:
---------------------------
The Black Knights
Pink Robin

Thank you.
