After compile, spawnable actor is stuck in spawned state

1. Create a Blank Project
2. Create a BP and add a cube to it (DO NOT compile it)
3. Add the Cube BP to the level
4. Create a Level Sequence
5. Add the Cube Actor to the sequence
6. Right click it and Convert to Spawnable
7. Move the Slider outside of the play range so the actor becomes unspawned
8. Open the CubeBP and compile it
9. Drag the time slider through the sequence

Result: CubeBP is now permanently not spawned. If you'd compiled while it was spawned, it would never unspawn
Expected: CubeBP behaves normally by spawning and unspawning when you enter/exit the play range
