Why Red Lettering in Sequencer?

I duplicated one of my scenes in Unreal. I did some minor keying/ change in the sequencer per scene. ie> (below)
Scene1, Shot1 keylight set to 1.
Scene2, Shot1 keylight faded, etc.
Animation meshes were never touched.
I assume it means the items/ meshes/ anime are missing however they were not. Can I relink it somehow?

Yes, you’ll need to relink if you duplicated the level. Click on the wrench icon and look for Advanced->Fix Actor References - that links them by name.

Thank you Max.
