Stuck at Gold 1 after 21 Wins

Hi, not sure if this is a bug or just a lack of transparency in the rank system, but I have won 21 games, have a positive win rate (+64/-56), my stats can be compared to people higher ranked than me, and I have consistently won games with people of higher rank than me. I know that you don’t necessarily rank up after winning 7 games, but this is a bit absurd. I don’t really see any incentive to play competitively if my rank cannot be influenced by my wins. Thank you.
