Invoice Form Personalization Warning Message Issue

Hello Expert,

I have done form personalization on Invoice Batch >> Invoice page , It contains Warning message when POP number and Requester is blank for specific Line.

It works fine but my problem is I need to click 2 times for closing this warning message. It should be close on one click.

Condition Tab :

Trigger Event : WHEN-VALIDATE-RECORD

Trigger Object : INV_SUM_FOLDER

Condition :  :SYSTEM.CURRENT_BLOCK ='INV_SUM_FOLDER' AND :system.record_status <> 'QUERY' AND ((:inv_sum_folder.requester_name is null) or (:inv_sum_folder.quick_po_number  is null) )

Processing mode : Not in enter query mode

Action Tab :

Type : Message
