Client Bug (Not a huge deal)

Experienced a weird client bug when viewing another persons mastery pages, then hit the home button to return to the team builder lobby. My mastery pages were named the same as his even though I didn't have them ever named that. However, upon hovering over the page it displayed the correct name in the popout to the right. Just a weird bug i saw not sure if anyone else has seen this.

Ps. This was done after I had already selected champ and runes in the solo lobby of team builder.
