[Pro]Theme menu keeps closing when using Responsive Menu Pro

Hello hello,
I first tried your free version which worked fine except for one kinda big issue. I then purchased the pro version (ID: Planta) but it still remains unsolved.

I’d like to use your menu as a secondary menu but it breaks the first main one. When I click on my theme menu it immediately closes itself…
You can see it on this page for example: http://haaitza.com/chambres

I thank you in advance for your help.
