Hello,
Thank you very much for choosing our theme and for contacting us.
You can hide the social icons in the Theme Settings > Single product > Elements.
Have you solved the issue with the bundle product? If you have not, insert the site admin access into the Private content below the message area.
The child theme is necessary if you are going to customize the theme. If you are not going to customize the theme, you would better use the parent (main) theme.
If you have any questions please feel free to contact us.
Best Regards
