BP successfully compiles, but compile sign remains "dirty" after adding a "Key Get Display Name" node to the character Blueprint

If the use adds a "Key Get Display Name" node to their character blueprint, the compile button will not update to the green check mark. It continues to show the Orange box with the question mark (as though it still needs to be compiled)

1. Download the attached project
2. Open the project
3. Open the "Neon_Character" blueprint
4. Notice that it is compiled
5. Add a "Key Get Display Name" node
6. Compile
7. Notice that the blueprint will no longer updates the compile icon to a green check mark
