I already have a 'Hybrid Chess' invention, on a 'Private' Rules Page. This may show a more general problem with having it Private, if it does not 'count' as a taken name in the database yet, and/or no one else but editors can see it.
A separate, longstanding, possible issue, almost, is that a CVP member can make a [preliminary] settings file with a name for a CV chosen, and it doesn't yet count as a name for a CV in the database.
