MIL-STD symbols cannot be added/re-added to an overlay after editing

[rikim1228]

Pre-requisites: Have the EMP3 Web SDK Validation loaded in your browser with a map engine and an overlay created and added to the map.

1. Open the "Create a MilStd Symbol" form by clicking General -> Create Mil. Std. Symbols from the side menu
2. Using the Symbol Explorer select a MIL-STD symbol
3. Fill out the following fields: Name, GeoID, Positions, and Unique Designation 1
4. Click the "CREATE SYMBOL ADD TO OVERLAY" button (the symbol is added to the overlay and made visible on the map)
5. Go back to the side menu and select Map -> editFeature
6. Select the feature/symbol just created and click the "EDIT" button
7. Make geometry edits to the feature/symbol and then click the "COMPLETE" button when finished
8. Go back to the side menu and select Overlay -> removeFeatures
9. Set the "Delete from" dropdown to the proper overlay, selected the symbol/feature, and click the "DELETE SELECTED FEATURES" button (the symbol is removed from the overlay and map...but, as intended, still exists in the repository)
10. Go back to the side menu and select Overlay -> addFeatures
11. Attempt to re-add the edited feature/symbol back to the overlay

SIDE NOTE: I have noticed that sometimes this makes it so that the features cannot be deleted from the repository...but this is inconsistent.

Expected Result: The feature/symbol should be re-added to the overlay and made visible on the map.

Actual Result:
