- I see a Fillet or Chamfer has a red-X error because one or more affected Edges no longer exists.

- I click Edit Feature.  I want to reselect new edge(s) to be Filleted or Chamfered.

- under Items To Fillet/Chamfer I see the green ***Missing Edge*** item.

- I click the ***Missing Edge*** item

- press delete key to remove it.  No response!

- click the Missing Edge a SECOND time

- press delete key. Now the missing edge goes away.

- click other edges in the model to add them to the Items To Fillet/Chamfer list.

This seems like a bug.  Why do I have to click the item TWICE before I can delete it from the list?  Any other program and I could click it once to select it and that's all it takes.
