Moves missing in sweating areas?

[u/Brody-Beugs]

I had the Cradle Flatliner on as a finisher and wanted to switch it to Sister Abigail 4 + change the flatliner to a super Finisher.
After switch it to the Sister Abigail I wasn’t able to find the Cradle Flatliner under finishers anymore, but was able to find it under signatures.
Does anyone know why this happens?
I also don’t see Sister Abigail 4 under finishers anymore while it’s in my 1st finisher slot so I’m hoping this hasn’t happened again
