I am using the same version and I am aware of the edit list you mentioned but it does not show the items I want to remove.
Not sure why that is the case however.
The "don't include" recent entries does work but also removes entries that I would like to keep.
Perhaps I am asking for too much.
This functionality used to be there, and it worked. Now the drop list shows nothing. There's nothing to edit (3056).
To the IK staff: if a feature works, please, leave it alone. Some of your recent tweaks were blunders, and every other build we download is a fix to a screw up from the prior build.
