Princess and the Frog reference at Fairytale Hall (intentionally?) wrong

Most of the book titles in the meet-and-greet room are accurate to the original language. But "Küss den Frosch" (which means "Kiss the Frog") is not the title of the original tale from the Grimms' collection, which is the most famous of the fairy tale collections. 

In Grimms, the title is Froschkönig, which means Frog-King.

I guess the real title would have been a distraction from the female heroine?
