Users Status changed after update

Hello, after updating to the latest version of UM, from the previous version, the user statuses have changed and only less than 10 are approved, <span style=”text-decoration: underline;”>when we have thousands approved</span>.

1. This is only one example, we have 4 sites using UM plugin and all are facing same problem:

All (5624)
=> Approved (6)
Pending Revision (0)
Pending Email Confirmation (0)
Inactive (15)
Rejected (46) |
Companies (561)
Candidatos (5.062)
Admin (1)

The database update was successful, we did not face any problem, but now our users cannot access the system, because they are not shown approved.

2. We are facing too another problem, now we have users that have no access to registration, inexistent, and that where not showing up at users section before, and this is happening in 2 of our 4 websites:

All
=> Editor
=> Autor
=> Colaborator
=> Suscriptor
=> Translator
Approved
Pending Revision
Pending Email Confirmation
Inactive
Rejected
Companies
Candidatos
Admin

In the other 2 websites that show our userl list, they are showing correctly the one that we had in the past:

All
Approved
Pending Revision
Pending Email Confirmation
Inactive
Rejected
Companies
Candidatos
Admin

Why is this all happening, how can we solve this terrible situation after plugin update and return our sites as they where before, working properly and with our users correct list?

Thank you, please help needed urgently, we have a lot of traffic and now we are facing a lot of problems with this update.
