DNF After final whistle

On my 15th match in FUT Champs, I was removed from Ultimate Team after the final whistle had gone in my match. Instead of seeing the usual post-match report etc. "Leaving Ultimate Team" came up and I was taken to the main menu. When I re-entered Ultimate Team, I was given a DNF warning message. 

I was winning my final match 3-2 when the final whistle went. Instead of being awarded 10 wins, I was given 9.
