¿How to fix the responsive menu in boostrap?

Question

in the inner page of this site the responsive menu is not working because I have to change the main menu in the inner pages (not in the home). When you turn on the inspector in your browser and activate the responsive mode, you can see the issue. So ¿How to fix the responsive menu in boostrap?

You can see it here

PD: In the home page the menu works fine.

Any help Will be grateful. THANKS
