Level Sequence errrors after conversion from matinee

I inherited an old project that needs some updating. It was originally built using matinees. Now that the matinee editor is no longer available, I must convert these to level sequences. I followed these instructions:

Some parts of the sequence are working, but there are quite a few errors.

  1. Every Visibilty track is showing in Red. Mouse over doesn’t give any hint to the error. If I add a new Visibility track it is not red and extends past the start and end points. The converted Visibility tracks only cover a portion of the timeline.
  2. There are multiple tracks for StaticMeshComponent0 that are red. Mouse over shows “The object bound to this track is missing.”

Is there anything I can do different during or after the conversion process to mitigate these issues?
Any other tips for migrating from matinee to level sequence are appreciated!

Thanks!
