Issue: Category choser does nto clear after adding a category

When I type in a term the category chooser correctly displays the categories in a drop down to chose from.
After selecting on, the term stays in the text field. Its not cleared. This causes the drop down to still display. This overlaps the chosen category which makes it not visible for the user to see that the category was successfully selected.
This causes the member to try to find the category again. But the category is not displayed again (which is correct)
This causes the user to give up on the page and leave.
