gridfx button appears in front-end submission form

[Dreamer]

Hello my problem is

1.I found gridfx quick button automatically appearing in front-end submission form (alongside media button) and back-end page edit from (alongside media button) for everyone , how can i control to display it or not for a user role ?

2.i insert gridfx shortcode inside ubermenu’s submenu, and gridfx content caused stacked grid on left side when switching ubermenu’s main option to another main option, how can i solve this problem?

3.if i want to customize gridfx theme CSS, how can i do?

sincerely
