"SETUP Di2 BUTTONS" prompt- how to disable the prompt?

Hi All,

When my 830 connect to DFly a prompt pops up asking me if I wish to setup the buttons for Di2.  My buttons have already been setup.  Is this a bug?  It's really annoying and the prompt doesn't go away until I tap 'X'.  I searched the Garmin forums and found a one-year old post with the same issue on a 820.  There was only one reply and no solution.  Is Garmin aware of this issue?  Why does the prompt come up even after all of the button options have been setup?  Thanks.
