For some reason, be it bootstrap or blocs, all mobile menus fire at the same time. It’s very easy to replicate this problem. Simply make a new project, add in two navs (they do not have to reference the same menu, and it makes no difference whether they are in the global areas or not) and preview. Next, go to mobile mode, and click on either of the hamburgers. Both menus will open. This is obviously bad.
It is important that I have two menus on one page, so it is critical that this problem be either fixed in an update or I find some way around it. @Norm
