Website Issues

I have had faced some challenges when building this website, despite using a premade facility which has really helped to reduce the workload. However, when previewing the website, it displays a lot of empty space that Wix will not allow me to edit/cut out. This has made me need to rethink this layout that I have originally chose in order to produce the best outcome.

As you can see in the video below, there is a lot of free space which makes the website look almost as if it is empty or unfinished which is not how I would want it to come across to my audience.
