Enter does not remove item from being selected

[jcrawfordRI]

I have found when using this component everything seems to work based upon selections except for when I want to remove the item from being selected. I am not allowing multiple selections but when a single item is listed in the drop down and I expand the contents it says hit enter to remove, however hitting enter does not remove the selection.

Is it possible to remove the selected item when I am using the select for a single value and not using muliple?

I have googled and found that due to using Objects the track_by has to be in place for the component to know which one you are de-selecting and I have verified that all 4 of my drop downs have this attribute but NONE of them will allow me to deselect the selection value.

The above images show the select element where it says I can hit enter to remove and the other two images are the props passed down to the MultiSelect component.
