losing LP on a win

So I was playing a match and at the end just before I clicked home I noticed it looked like I had lost LP on a win. I shrugged it off as misreading it in a brief moment and joined my next game.

There is a screen attached of the next win. +25LP for a total of 27.

Now in two wins one of which is +25LP it's not possible to get 27. Yes you could get +2 LP off the prior win but nobody ever gets just 2 LP off a win i Gold V. I've never once recieved less than at least 10-11.

It seems I really did lose LP when I won a round (i'm also quite sure the first win actually started higher than 2 LP and lost LP not win.)

Anyone ever heard of this, have a reason I might be wrong?
