Ranked Team Stat Glitch (3s/5s)

Before the most recent update that changed the layout of the profile page into these two sections, one for champ mastery and one for your own things. The one for personal stuff like your own cs, take downs etc was the first thing you see (when you haven't done ranked that season) But in this update it seems there's a glitch where if you joined a ranked team and played none of the matches with them (or all of them) and then the team is disbanded, you KEEP the stats. So say you joined a team to put some points in for this season ward or something but do poorly, those stats stay even after the team is gone.

TL;DR ranked 3s/5s team stats don't disappear after the team is disbanded
