TypeError when index-onepage-2.html + slider-revolution-kenburns.html

I trying to add the slider-revolution-kenburns.html in the index-onepage-2.html because of the submenu feature, well after get everything working as I want got the error:

TypeError: swiperSlider.update is not a function
/Demo/js/functions.js:1529

And that is because in the class of the slider section I using swiper_wrapper instead of revslider-wrap because if I use it, the submenu don't attach to the main menu after scrolling the slider and disappear and the shows again until the Work section is scrolled instead of the About section, I only get the correct behavior with swiper_wrapper but get the issue detailed before, I attach a html demo with the error described that can be placed in the HTML and reproduces the issue.

Thank You in advance for the support.

The file compressed because plain html not allowed.

I uploaded the demo to http://hakeny.com/

Also removed the .slider-parallax-inner container as recommended but there is still the error:

Uncaught TypeError: Cannot read property 'removeAttribute' of null

And there are 2 warnings:

• Calling Element.createShadowRoot() for an element which already hosts a shadow root is deprecated. See https://www.chromestatus.com/features/4668884095336448 for more details.

• Handling of 'mousewheel' input event was delayed for 101 ms due to main thread being busy. Consider marking event handler as 'passive' to make the page more responive.

And sometimes the scroll experience is very bad and I suppose is related to the mousewheel warning.

Thank you for the support.
