When I update the css was modified, to solve it I had to modify in the class .col-1 and .col-2, which added the flex property; and it is solved. but I am concerned that I continue to have this or other problems.
Also, I just read in a blog in Spanish that generatepress 3.0 loads the site slower due to these flex properties
But just the page that inserts those css, I did not do it with beaver builder, this is the woocommerce data registration page. I imagine that beaver builder inserts in general css
