Sort Icons In Grid Header Not Showing Up

I have the following grid:



When I click on a header the sorting icons are not appearing although they do exist in the specified directory and the sort is working. Any ideas as to why the icons are not showing up?

Such problem may occurs if grid can’t find sorting images in the specified folder. Could you send us example including all files which you are using where we can reproduce this isuue.

I sent the files but I don’t see it showing up in the question.
