Sort Arrow Issue

[adyfoot]

Hi everyone,

My company is using PnP Modern Search webparts on our intranet. We have installed the latest version 4.11. We have a page that uses search to display corporate policies and documents. Until now, the page didn't have any sort ability. We've successfully implemented the sorting but are seeing weird sort arrow behaviour. Usually, sort arrows will appear on the sorted column and indicate the direction of the sorting. What we're seeing is that sort arrows appear on all columns that have sorting enabled - please see screenshot:

Are doing anything wrong in the way we've set this up? Or is it a bug? Here is the XML of the search webpart configuration if that helps.

webpartproperties.json

Thanks in advance!
