Licensed Zoom Account added to our organization reverts to basic.

I inherited a zoom admin account at a new job. I am not a zoom expert... The account type is shown as PRO. It has 5 paid licenses for 5 users in our company all who have the same domain name.  I invited the other employees of the company to the zoom account, everyone has the same email domain name. Some employees had setup paid Zoom accounts with their domain email in the past (not part of the 5 mentioned above). When they accepted the invite those paid accounts show in the organization as basic. If I remove those new accounts that are licensed and they login into them the account shows as licensed. It was my understanding that under these circumstances, those paid accounts invited in would retain the license that they have paid for. What am I missing?
