Question on Character Amounts?

Was looking back on Blue posts and saw that I should have 50 characters available to create for both Wow Retail And Classic. Did they limit the amount you could have prior to launch on Classic?
I have 3 characters waiting on classic, making my total for my account sitting at 20, which is 30 less than Max for the account. But when I try to make a 4th on Classic / 21st overall it says you have reached your limit? Anyone know?

Never mind i found it. Thanks anyways.
