I'm not sure why it's showing like it is. Normally the social toolbar is on the left side and all horizontal, not stacked like that. It also only shows to super administrators, just so you know.
Regardless, of how it looks, right now there's not an option to completely disable it. There will be an option in the 6.1 release, due later this month. Until then, if you want to make a code change to disable the widget, please
follow the instructions in this post
.
I hope that helps answer your question, but if you need more assistance, just let me know.
Thanks,
Alex
