I don't have the Simplified theme, but see if you can activate the default (boring) theme or a free theme you enjoy if only for a while to see if the icon appears twice there, too.
As soon as you know, I'd contact the developer of Simplified to let them know it might be their issue.
A supercharged BIS? Like 5G? That'd be sweet. Redundancy and everything to ensure there's never an outage.
I occassionally get this double logo also and am on a different theme. I never noticed any difference in performance so I assume its not important. Maybe a theme builder issue ?

That's my guess too. Seems like the BIS icon is quite flaky on custom themes. In adidition to the issue in the OP, I've noticed that the BIS icon on the homescreen often is absent - even if I have a connection (according to service staus screen)
