Not losing hp when defeated bug?

Has anyone else had an issue where, you win a round and defeat your opponent but they don't lost any hp? I was kind of annoyed when i played ranked today and was in second place with about 16 hp, 3rd had 5 4th had 2 and 5th had 1. I then proceeded to beat both 5th and 3rd place players fairly one sided and yet neither one of them lost any hp after the round. Then in the 3rd round it placed me against the first place player who had 6 nobles and 2 glacials and i got booted out and took 5th. It's pretty frustrating to come in 5th place and get nothing when by all rights you where the second strongest in the match.
