You sure noticed that this is a two time repetition?
There are zillions of posts in the forum, which will explain it.
And this 0.00 will be showed only with the move history of the pgn,
if you load the plain position it will show the true score.

The only slighly remarkable is that Stockfish despite a score of +2.24
started the second repetition instead of the immediate 46. Kg2.

I had not noticed this many thanks, as you say pasting the game position shows the true score.

What do you think went wrong in this game? evals were strange.
