An issue that has failed to be adressed

Has anyone else been having trouble removing things from their favorites, tracking, and 'read later' lists? Because it's been six months now and I've brought this up with every authority figure I could find on this site, and I still can't remove anything from those lists. It just keeps sending back an error. And no one I've messaged about it has replied.

Any one with any suggestions about what i'm supposed to do when the site staff is perpetually ignoring me, or who have been afflicted with a similar issue, please lend advice.
