Indirect Lighting Not Working After Updating

My indirect lighting source, which prevents my shadows from being pitch-black, no longer is working after updating my engine.

I don’t understand why.

I went to “reference viewer” on both the old (10.4) and new (12.5) versions of the light source and noticed this difference:



So it seems like there is a difference. For some reason the second light source BP isn’t connected to the level? Why? It is in the persistent level…

Please help.

Any ideas??? please.
