Enabling plugins breaks the header and main menu in Hueman Theme

Hi and thank u for your great plugin. I want to use One click Accessibility with Hueman Theme but when i enable the plugin it breaks menu and a part of header.
The toolbar icon is 52px and after enabling i see a gap in header and menu (i think the same height).

When i deactivate plugin everything comes back to normal.
Thank u very much
