A contact form and a gallery on the template are not being

Hi,

Woocommerce products, contact form and gallery on the template are not being copied over to the new blog. I've checked all the 'additional tables.'
I had to restore backup snapshot multiple times, and since then the new blog template isn't working as it should.
I'm not sure what exactly, but something is wrong with the new site creation process (sites -> add new).
I occasionally get error saying "already installed. to reinstall please clear your old database tables first." Also, when I deleted the site and tried to create a site with the same name, it said the site still exists.
I just want to restore the site to how it was before.
Could you please take a look? My support access is on.
Thank you so much,
