backend editor issues – changed to blocks, header issues, now store front issues

I have 3 main issues and I have tried every possible fix on the child theme and backend.
1. The biggest issue is that I updated my wp theme and now my backend is showing everything in editor blocks. I can’t edit my template or add info with these blocks. This one has stopped my progress. I’m not 100% it was the wp update but it seemed to happen around the same time of day.

2. Header issues: My slider and header photos are going behind the logo/nav area. I need the logo/nav area to be a solid black so that the social networks and nav links are visible at all times. I have changed the child theme numerous times and tried every scenario I know how to and can’t get it to work.

3. The store / product was working fine but now the page is showing the price of the item three times. And now it’s duplicating the products/rows/columns below the page, just above the footer. Please help.

I purchased extended support and will be happy to talk to someone one-on-one. My login info is below. I need to get this up and running today. I need to show the client the site tomorrow and the site was 95% complete now everything is mixed up and not working properly. Thank you for your time.
