unable to select icons in front editor

Hi,
I have a small problem. I am using floox-template and sp pagebuilder pro. I want to edit the slider on the home page (your connection to creativity in just a few clicks) in the front page editor. When i move the mouse to the uppper left corner to click on the edit icon in the green bar, the icons disappear and can't be selected. This also applies to the icons in the blue bar from the row in which the slider is placed. What am I doing wrong?
