Home page messed up with Elementor – trying to restore

Hi – the folks who designed the site home page left no documentation when they left. It has a slider at top then typical two columns. When I went into it, there were two CMS prompts. Edit with Cornerstone and then edit with Elementor. I tried CS first and it was fine.

Later I went back in and tried Elementor. I made no edits to anything but just left it. When I did so, the slider and page slides left and right when you scroll down. I also noticed that the title changed and now has the word Elementor in it.

I’m trying to figure out how to restore the page to its previous version. I do not use FTP. I’ve looked on Google and there are a million ways to do this with plugins and so forth so I’m asking is there a very easy way to simply restore this page to what it was before Elementor xxxxxxxed it up?
