1. Download, unzip, & open the project in this folder: (See comments)
2. Once opened, open the 'AdvancedPlayerCharacterPawn' blueprint
3. In the MyBlueprint panel, create a new variable named 'Test'
4. Set the type to ArmorStruct (Screenshot #01)
5. Place a 'Get' node of that variable in the Event Graph
6. Drag off of it and create a 'Break ArmorStruct' node
7. Click the arrow dropdown to see all of the struct values (Screenshot #02)
8. Compile & save
9. Close the editor
10. Reopen the project
11. Open the 'AdvancedPlayerCharacterPawn' blueprint & look at the 'Break ArmorStruct' node

Results: The 'Break ArmorStruct' node will now display a string of letters and numbers after the value names (Screenshot #03)

Expected: For the value names to display correctly
