Entering a customer name resets other fields in AgentTicketP

[Bartas]

Hi, everyone,

I use multiple ticket template buttons in AgentTicketPhone. These are working well, except one issue:
if I set any Dynamic Fields or Destination Queue using template buttons, they become reset after selecting customer name. Other fields are not affected.

The code in AgentTicketPhone.dtl:

# ---- Template button ----
<label>$Text{"Templates"}:</label>
<div class="Field">
<button type="button" onclick="$('#Template1').submit()" value="$Text{"Example Template"}">$Text{"Computer"}</button>
</div>

# ---- Template form ----
<form action="$Env{"CGIHandle"}" method="post" enctype="multipart/form-data" id="Template1">
<input type="hidden" name="Action" value="$Env{"Action"}"/>
<input type="hidden" name="Subaction" value="StoreNew"/>
<input type="hidden" name="FormID" value="$QData{"FormID"}"/>
<input type="hidden" name="ExpandCustomerName" value="1"/>
<input type="hidden" name="Subject" value="Computer "/>
<input type="hidden" name="DynamicField_producttype" value="computer"/>
<input type="hidden" name="DynamicField_productname" value="Serial number:
"/>

Please help. I'm stuck on this...
