'Persephone' contains profanity?

In my current playthrough, I'm naming my horses after deities from greek mythology. For example, my dutch warmblood is named Calypso and my missouri fox trotter is named Artemis.

I decided to name my appaloosa Persephone, but it said it contains profanity. Idk if it's because my first language isn't English, but I can not see a profanity in the name.
