Page Builder Questions

Hi. I’m using the new page builder and am pleased with the functionality it promises. A couple of issues that I’m hoping someone can help me address.

1. The Prebuilt Layout doesn’t seem to work for me. I get the pop-up window, but nothing loads and it just spins forever without loading options. I tried disabling all other plugins but that didn’t resolve the issue either. Any suggestions?

2. When I add in an object such as a search box. The settings appear at the bottom of the page instead of loading in a pop-up window, which is the way other page builders I’ve used work. Is this the way it’s supposed to work?

Thanks so much for any direction.
