Out of 9000+ active Bento installs this seems to be the first time this questions pops up, so probably not that many ?? In any case, please take a look at the custom CSS snippet you can use to get rid of the logo element completely (to be added to the “Additional CSS” tab of the “Appearance -> Customize” admin area:
.logo { display: none !important; }
Or, if you want to hide the logo visually but retain its container on the page for the purposes of layout:
.logo { visibility: hidden !important; }
