Quicksearch "assigned to" is broken

Hi all.

I use SuiteCRM 7.11.8 and I got a problem with the quicksearch for “Assigned to” field.

I saw the problem in Calls module > Log Call.

Before, I could use Quicksearch feature without problem but now, it does’nt work, and I don’t know why :frowning:

In browser inspector, I see one input with the quicksearch working with classes “sqsEnabled yui-ac-input” :

<input type="text" name="parent_name" id="parent_name" class="sqsEnabled yui-ac-input" tabindex="0" size="" value="" autocomplete="off">

And my input “Assigned to” do not have it :

<input type="text" name="assigned_user_name" class="sqsEnabled" tabindex="0" id="assigned_user_name" size="" value="" title="" autocomplete="off">

I tried with a SuiteCRM demo, and fields got both classes “sqsEnabled yui-ac-input”.

I don’t understand how fix that. My customers used this feature, and now it’s a problem for them.

Anyone got an idea ?
