Incorrect Host Name Display in FortiAnalizer

In FortiAnalizer Reports, I'm getting the wrong hostname in reports such as the "Top Bandwidth Users" report. In the Firewall Users session of Fortigate FW, I'm getting the correct hostname

Fortigate and FortiAnalizer are connected with FortiAuthenticator and which is connected to the AD server for user authentication. Please share any solution/suggestion for the same.

Q2:- We are getting the Hostname and IP address in FortiAnalizer Reports, Can we also get details like the User Display Name in reports which is configured in the AD Server?
