[xwiki-users] Help me again ;)

Hello, I'm writing in connection with the same problem as last time... I have double buttons on the top panel. Could you tell me how to hide this or switch off? I have cleared cache of my web browser, installed and deleted extensions of XWiki... all don't working. Please help me. I will really happy if you sent me screen shots or something to show me how to do that. Screen shot with issue in attachment. Greetings, Maciek.
