Hi- I have 2 issues.
1. When the module is active on my page, it's changing the font size for my entire page. It's making it too small to read).
2. Can I create a link icon on pro version like standard version has.
I have checked and fixed the font issue on your site.
For the load more button, please assign module to menu on the "Menu Assignment" config. If you are using the Page builder, you don't need to assign the position. Now it works fine.
Please recheck it.
