XF 2.1 Transparent box next to logo on mobile

Hey everyone,

I am brand new to Xenforo. I made some Phpbb forums years ago but have found that I am pretty rusty. I recently uploaded a new logo which looks great on desktop, but for some reason on mobile there is a little transparent box next to it. Any ideas on how to get rid of this?566600D7-4EDB-4E6B-97F0-B36712786C88.jpeg
