Problem with "ImageUpload" addon

Prosper

I have an instant of hidden "ImageUpload" addon on the far right side button. This appears only on firefox and IE explorers but not on chrome. Please see attached screenshot to understand what I mean. When you click on the hidden space, image upload folder pops up. This is abnormal. Does anyone know how to solve this problem? This happens on vanilla version 2.1.11.

Please does someone has a clue how to fix this problem?

I believe this element has a CSS class. If so, you can set it to display: none

I have already used firebug firefox browser addon to check it out and add display:none but did not solve the issue. Is there any other thing I can do?
