Is Ceratioidi a language?

[Laird IceCubez]

In Kingmaker: Rivers Run Red (Part 2), Ceratioidi have their own language called Ceratioidi.

Then in Bestiary 3, which came out later, the Ceratioidi speak Aquan instead of Ceratioidi now.

Cause I'm compiling a list of languages in Pathfinder and I want to know if Ceratioidi has been retconned.

I know daemonic from Adventurer's Guide was a typo, but is Ceratiodi retconned to no longer be a language?
