Can you help me with search results?

I was previously using Post Grid with Elementor, ACF, and Search & Filter Pro. Does the new version work with these plugins, or only Gutenberg Blocks?

My search results page has 2 issues. The more important one: it shows the search results, and then underneath them it shows all posts. That's fine, but I need a title in between the two so people know that everything below the title is NOT search results.

Second issue is the slider bar on that page - see how it sticks out of the box?
