Very good – one thing…

Could you please update to the latest version (1.12) and tell me if that fixes it?
If not, a screenshot would be greatly appreciated!

got it and fixed it.
I’m not going to release an update for this yet, I’ll wait till some more things are added. If you want a quick fix until I update the plugin in www.ads-software.com you can open up the wp-content/plugins/bootstrap-admin/assets/css/compiled-style.css file, delete its contents and paste in it the contents of this file: https://raw.github.com/aristath/bootstrap-admin/master/assets/css/compiled-style.css

Or you could simply paste at the end of your existing file lines 7192-7195 found here:

https://github.com/aristath/bootstrap-admin/blob/master/assets/css/compiled-style.css#L7192

#adminmenuwrap #adminmenu .menu-icon-feedback div.wp-menu-image {
  background: none !important;
  background-image: none !important;
}

I see you did a 1.13 update.
I now see the above code in the file.
But I’m also still seeing overlapping Feedback icons.
No biggie. I like the plugin.

Stop press – after quitting and re-opening the browser, the issue has gone away.
