mistake in lessons

Hmm.

Which lesson?

name of the lesson: "How to protect the king"

and if I asking for help assistant said: "how to put knight on safe bord and prepare protection weak pawn on h6 in future rook ending"
but there is no knight)

I found mistake in russian language app, mb in english all right, I don't know

This must be where they came from-- the challenges from "Defending the King."

I'll take your word on the mis translation. I would send a bug report or an email to support@chess.com with the screenshots to help them find it.

"конем" means  knight)
if you put word "конь" it in translaitor you'll see the word "horse" becouse in russian this chess piece  is called horse (couse it looks like it) so =knight = horse= конь)
and on the bord is bishop  it names in russian "слон" if translate word to word in english will be elephant)
=bishop=elephant=слон
so fun story)

yes in this lesson) in english everything is correct

thanks for adwice
I wrote to them.
