Kallyas Pagebuiler Issues?

Hi. Totally new here. Not sure if this is the right place for this topic.

I have a site using the Kallyas theme. I had not problems with it when pages were built using admin on the backend, but since the introduction of page builder, seems every element is broken and I am wondering if anybody else has had issues using pagebuilder with wordpress.

Of course I consider that it must be me, as I know so little about website construction.
