Error displaying user - normal user

Hi, good morning. I’d like to see if you can help me with the following problem:
I have a SuiteCRM 7.14.6 installation, which came from a migration from SugarCRM 5.6.
In the Cases module, I have assignee information and data that shows the name of the user who edited/modified the information.


However, now in SuiteCRM, I see that the user is no longer displayed at startup, and I can’t select any values ​​when editing.
In addition, the information where the user name was previously displayed now includes the user ID:

Could someone help me with this problem?
I ran a couple of tests, and it only works and displays the information if the user querying is an administrator; if not, it doesn’t appear.
However, I require this not to be the case, since I can’t make all users administrators, and I need them to be able to access the user list, view their names correctly, etc.

Do you have any roles set?

Was it working before? Make sure user is assigned to the role & security group, if you have any.

I would check the database to see if the user’s table is properly created and that it contains the valid user ids and matching user names…

This looks like a faulty migration…
