Hi mfall87,
Thanks for the screenshot. Seems you already have a rounded corner applied to the top and bottom corners of that shape but with the Corner type (in the context toolbar) set to Straight. You then added two additional nodes to the end of the chamfered line on each corner and are trying to now round these corners as well.
To do what you want, you have to delete the two additional nodes you have added, so only the main straightened corner remain. Then with the Corner Tool selected press the Bake Corner button on the context toolbar to permanently change the geometry of the shape, then apply the Corner Tool again on each of the resulting nodes. See the clip below (no sound).
