Board Game Arena

Hi! I don't quite understand how the game scores cards -- I counted only 38 on my cards here, but the game awarded me 40: https://boardgamearena.com/table?table=946785612

Opponents' points are also off by a couple of points.

Can someone please clarify what I am missing here?

Thank you!

I see 40, your 4 X cards are worth 16, your negative 3 is actually positive 3 and then just add everything else up is 40. The terrain card is worth 2 maybe you missed that.
