Advanced filter cannot be updated

Hi all,

I have a bookmarked report with downloaded files to which I want to add a file. I've added this file to the advanced filter, but it disappears every time. It seems I cannot update the filter for that report anymore. The filter contains 43 items at the moment. When I clear all and add the new one it does work. I just cannot add any items or change the current ones.

I've tried another bookmarked report and that was not a problem.

Kind regards,

Ingrid
