Hide Empty Column in Forum topic List View not working

Hi Guys,

If I make a new filed in the view advanced_forum_topic_list, and I add a Global Text, totally empty (so no value in there), then it will show up in the column list as Custom Text with no value in it (as it should). Now I want to hide empty columns. So under Format=> Forum topic list Settings, I select the Hide Empty Column on the Custom Text, but it is no hidden. It seems this functionality is broken.

Best regards,

Geert
