does not work in SiteOrigin page builder

Hi, I am looking exactly for this plugin – but I found problem. It works correctly in sidebar widget area (I am using Zerif lite theme) but incorrectly in page created by PageBuilder. There is not possible to ADD new link, so limit is only default 3 links. Is it possible to set-up number of default links to make some round-about?

Thanks, Martin
