The account/username registration311 can have up to 10 sub-users. I checked this on the account and I see that there were only 4 sub users added so far. So 6 more can be added.
I test adding a sub user and it was good. I did not encounter the issue you mentioned.
Can you please retry. Make sure you are actually logged in to the correct account at https://www.jotform.com/login
Let us know if issue remains.
