Hello,
1) If you like Underwear contact page and want to import it go to Theme Options > Import/Export > Additional pages import > http://prntscr.com/iydrf0
2) Looks like theme options were not fully imported. Can you provide me temporary Dashboard access to check?
3) Either disable WooCommerce Infinite Scroll and Ajax Pagination plugin (if you don’t want to have infinite scroll for products) or sett correct settings https://www.8theme.com/documentation/xstore/plugins/woocommerce-infinite-scroll-and-ajax-pagination-settings/ (if you want to have it).
Regards
