Hello Maurice,

Sorry for the delayed reply. I have checked it on my development server and it is working fine. You can check it here:

Please let me know where you put this code or is there any chance you have modified it? if not, Please try to debug after deactivating other plugins, custom code and switching to the default theme temporarily.

Please let me know if it helps or not.

Regards
Ravi
