Image Frame resizing problem in WordPress

I’m running the latest updated Avada theme for my website. I am using Fusion Builder to edit my pages. Whenever I try to add an image onto the page (using the Image Frame from the Builder Elements), the image always resizes itself down to the Large display setting, even when I have selected ‘Full Size’ in the Attachment Display Settings in the Insert Media window. It’s driving me NUTS. I’ve tried overwriting the image setting using custom CSS, but even when I can make it display a larger size, it just stretches the photo, still using the fixed resolution of the Large setting. I’ve also tried importing images using URL from Google Drive and Dropbox (both set to public), but I can’t get it to important the images. Any ideas what’s going on? I just want to display larger images on my pages in Image Frame.

The problem is with the quote located on the home page down on the first parallax image.
