Dynamic/Solo Queue icons not functioning correctly in Challenger

I don't really need to post pictures. my Challenger account 'silas kroeger' won merely 7 games with a duo partner, never, EVER dynamic queuing any other games for the entire season. Basically I don't ever play with anyone else except those 7 wins.

Basically, after these 7 wins, I was branded with the Dynamic Preference icon, even though that's not even remotely the majority of the past 25 wins. I had the solo icon before this proving that it was counting wins past 6.12 (I WON 40 SOLO GAMES AFTER PATCH 6.12 BEFORE DUOING 7 WINS) , but it got changed to dynamic after merely 7 wins. Makes no sense. Since, i've won ~20 games by myself and i still have the dynamic icon. Please fix or at least clarify details you maybe left out about how it applies in challenger
