ZM AJAX Login & Register modal and submenu

Hello everyone, this is my first post in the forum.
It has to do with a plugin with which I am working, ZM AJAX Login & Register.
I asked in the forum creator, but not give me answer.
The problem is that. I have a button in the main menu and this in turn contains a submenu button . When I click on the menu button a registration form appears in a modal and if I click on the button on the submenu two modals the login and registration appear . I think it has to do with the hover buttons because if I put the buttons as main its ok .
Anyone know how I can fix this.
Thank you very much
