Can't Remove icons in the open list

I up grade my clients from 7.x to 8.5. Most users have an icon in their open list for som etime off calendars. The database view get hosed. I usually just remove the icon, open up the database again from their workspace and create a shorcut to their open list.

Well, when I right click on any of the icons on the right side and choose to remove the bad icon, nothing happens

Has anyone come across this yet and found a fix?

Thank you,
