Unable to create more users

Unable to create more users

Hello, i already have 5 users. So when i tried to create one more, zoho alert me that i have to upgrade. So i pay for more 5 users. But i cant create, still with the same 5 users before. So i think that i have to pay + 5 users, so i will have 10. But i cant do that, because i dont have this option anymore, only to upgrade to other plan with the same 5 users. But i need more then 5
