Duplicated technicians after re-assign

Duplicated technicians after re-assign

Greetings,

We use ServiceDesk Plus 11.0 Build 11002 and PGSQL.

We have an issue with duplicated technicians after re-assign users to technicians. All users're importing from AD but before in use was LDAP.  After changing the import mode issue looks like this when we want to assign ticket to someone from the list we see duplicated technicians.

But in technicians list into the Admin looks normal:



Will be appreciate for any help.
