Edit limit client

Error: One or several limits you are trying to set already exceed the limits defined within individual domains belonging to this client.
The total limit for the client must be more or equal to the total sum of the domain limits defined for this client account.

My first guess would be that since 2gb / 5 domains = 400mb, you can't use 500mb as a domain-level limit.
