Is Really Draw by repetition

Its  bug or am completly noob here, how its draw by repitation ?https://www.chess.com/analysis/game/live/106844546153?tab=review

This is indeed draw by threefold repetition. Look at the board position after Black's moves on moves 23, 25, and 27. These are the same board positions. Remember that the exact same moves do not need to be repeated, only the board position needs to be repeated.

More examples in this official Chess.com article: https://www.chess.com/terms/threefold-repetition-chess

9.2 The game is drawn, upon a correct claim by a player having the move, when the same position for at least the third time (not necessarily by a repetition of moves):

9.2.1 is about to appear, if he/she first indicates his/her move, which cannot be changed, by writing it on the paper scoresheet or entering it on the electronic scoresheet and declares to the arbiter his/her intention to make this move, or

9.2.2 has just appeared, and the player claiming the draw has the move.

9.2.3 Positions are considered the same if and only if the same player has the move, pieces of the same kind and colour occupy the same squares and the possible moves of all the pieces of both players are the same. Thus positions are not the same if:

9.2.3.1 at the start of the sequence a pawn could have been captured en passant.

9.2.3.2 a king had castling rights with a rook that has not been moved, but forfeited these after moving. The castling rights are lost only after the king or rook is moved.
