Little issue with collapse bootstrap

Hi,

I must say that this plugin is really good, mostly because you can put it to work very easily.
My problem is that after activated the mobile menu sticks perfectly but when clicking (or tapping) the hamburger icon, the menu roll down but from the original position, not the cloned one.

Check it please: https://bit.ly/1L7fo8p

Do you have any fix for this?

Thanks in advance,

Bensita
