I recently loaded up Nosferatu on my Plex server, and most or all of the cast was born in the 1800s. I noticed that the numeric ages displayed on the actor info screens are not adding up from their birth and death dates, like Max Schreck, born 1879 and died 1936, and the displayed age is 34 years old instead of ~56.
I’ve never had issues with this before, and it appears to only apply to particularly old dates, like these.
