Loss prevented every morning ???!!!

I have been playing ranked every day for 4 days i play it too early in the morning like during the sunshine hours. and every time there is 1 match that i win and i get like 6-9 points for that win , not only me but the rest of the team too. same points and the enemy get Loss prevented , while there was no problem with any of the players it even happened to me once .. is it a bug or what? because getting that low LP isn't connected to my progress or any of the other players progress as the next match we get normal approx 20LP

Note: not on that account so you don't try to see the match history ..........
