Hello,
1) The map is not showing on your page because GMAPS for Visual Composer is not activated. You need to install Google map plugin (Appearance > Install plugins) or remove this row http://prntscr.com/mtwk3n from the page. If you decide to delete the map, please delete this margin also http://prntscr.com/mtwka1
GMAPS for VC element has API key field http://prntscr.com/czidd2 https://docs.brainstormforce.com/how-to-create-google-api-key-in-order-to-make-the-google-map-element-work/
2) You can add Products element in tabs – http://prntscr.com/mtwn1x
