Hi pavanjb
The issue seems come from the template you're using.
I just made a test by assigning default Joomla template - Protostar to the search menu item: Search by keyword global and assign K2 filter module (Showing (2) in 'position-7') to the same page
but it works properly: https://prnt.sc/sk390o
You can contact the provider of template for help on this.
Regards
