Points deducted for first place in Battlegrounds

I placed 1. in a Battlegrounds Match today and still got 38 points deducted.
This happend while playing as “The Great Akazamzarak”
After the deduction I now have 4625 points.
I understood from other posts that the MMR system was changed in the latest update but I think it should still be possible to gain points if you place first even if your opponents have a lower MMR (there shouldnt e a big difference anyways at this low MMR.

is there anyway to attach a picture?

Hoping for conclusive anwers
