"Collapse" Button in Bootstrap works only one time

Hi!
First of all thank you for great menu and sorry for my English.

In the top of my test Joomla 3 site I used Bootstrap's collapse navbar construction (when we open site on smartphone or tablett we can see one button instead of all menu buttons).
Before I had installed maximenu, this button worked normaly. But now it works only one time - I can expand (first click) and collapse (second click) maximenu and then button becomes not active. Then I must to reload page to button could work again.
How to fix this problem?

Hi

May I ask You try to use this construction on your computer? If your attempt will work normaly I will understand that in my PC something wrong.
Thank you.

sorry but I don't have the time to do some custom tests on my computer
