EVS restore to incorrect mailbox

Hi,

EV11.0.2 CHF2 with EV Service account restore the selected item to incorrect mailbox all the time by EVS.

Condition:

> Open IE with EV service account and the EV search link

> select user1's email from user1's inbox within EVS interface (IE) by EV service account

> Highlight and click restore to the original location, then it restored the item to user2's mailbox 

It happens to any selected mailboxes, it will restore to user2.

Please advise.

Many Thanks

Tony W.
