It is chess960, the pieces start on different squares. You are unrated at chess960.

Be more careful in future, when accepting challenges.

You inadvertently either created or accepted a Chess960 seek.

Chess960 is an alternate game type where the pieces are arranged in a semi-random order at the start of the game (bishops have to be on opposite colors, the king has to be between the rooks, and both white and black have the same setup).  As Chess960 has some major differences (the lack of significant opening theory, mainly), you have a separate rating for Chess960 than from the more usual chess.
