PartDesign: Deleting selection from dressup feature using delete key deletes whole body

Problem description

If I create a cube in part design with a chamfer on certain edges and then go back into remove edges by selecting the edge from the list and use the delete button, the whole body is deleted. If instead I right click and click remove, the edge is removed from the list.

Workbench affected?

Part Design

Steps to reproduce

1. Create a sketch on the xy plane and pad it the default value.
2. Select some edges and create chamfers or fillets. Click OK
3. Go back into the same tool, select an edge and press delete.
4. The whole body is deleted.
5. Click undo.
6. Go back into the tool and right click on an edge and select remove. The edge is removed from the selection.

Expected behavior

I expect the delete button and right click remove to just remove that edge/face.

Actual behavior

Whole body is removed.
