I’m experiencing the same issue. I’m commenting here in the hopes that the developers notice and address it. I included a link to the Necros video in my post; it seems this problem has persisted since the beginning of the season. However, it hasn’t been widely recognized due to the rank reset and the ‘Predicted rank’ screen replacing the percentage bar. I only became aware of it yesterday myself! But Necros posted his video on YouTube nearly a week ago, indicating the issue has been present since the start of the season.
