Units selected in Select Metadata sometimes show internal data structure

[rfrenchseti]

• Open the Select Metadata dialog.
• Expand the Ring Geometry Constraints and Radius & Longitude categories.
• Add a longitude such as Observed Longitude WRT Ascending Node (Min) to the metadata field list.
• Go to the Selected Metadata column and click on the degrees unit after the new field name.

Instead of seeing a dropdown list like "degrees, dms, radians" you will see an internal data structure where every character is a separate line in the dropdown.

However, if you close the Select Metadata dialog and open it again, the units field works properly.
