100% height color section doesn't fit bottom of the screen with sticky menu v2

Hello,
I already had this problem previously, but it could be fixed with your help here
Unfortunately the solution doesn’t seem to work anymore. Or to be more precise, not as expected. Since the sticky menu has a 150px height, I added the following code in the shortcodes.js file overiden in the child theme :

var newheight = wh100 - 150;
				css += ".av-minimum-height-100:not(.av-slideshow-section) .container, .avia-fullscreen-slider .avia-slideshow, #top.avia-blank .av-minimum-height-100 .container, .av-cell-min-height-100 > .flex_cell{height:" + newheight + "px;}\n";

Unfortunately, the section still goes further than the bottom of the screen.
Furthermore, since on tablets and mobile, the fixed header has a smaller height of 80px, I would need to also adjust it somehow….

Can you please advise?
Thanks a lot in advance
