Creating MORE than 3 susbscription TYPES


So im setting up a new membership site. My client has 2 access levels - either NON member, who can see limited pages, and then Members who get full access. HOWEVER, these paid members have subscription types. My client wants FOUR subscription types. BUT I can only seem to add 3. When I add a fourth, it says Cheatin Huh?

What the hell? Whats the point of only having 3 subscription types? What if my client wants to add more.

Please login, and fix what ever is broken. I need to be able to add unlimited subscription types.
