Professions Bug

I noticed this in the advanced search and the edit biography sections. It seems like professions are being created somehow by using a comma to put all professions as one entry instead of separate entries.

Here are the ones that have been made so far:
"Actress, Adult Model, Porn Star"
"Adult Model, Porn Star"
"Adult Model, Pornstar"
"Pornstar, Adult Model"
"Pornstar, Adult Model, Centerfold"

And here's a couple profiles it has effected so far:
https://www.babepedia.com/babe/Luisa_Fernanda_Chavarria
https://www.babepedia.com/babe/Shweetie
https://www.babepedia.com/babe/Sofia_Delgado

I have been unable to recreate the bug, so I don't know how it happened.
