Hello,
1) I checked your site and don’t see issue with the blank cart once I change the q-ty to 7 https://gyazo.com/f14c071572a4c21782c6fcce288f1482 Have you sorted out?
2) I don’t see any free product rule in the plugin settings https://gyazo.com/370b863e3a92d666c5bbabfa3cc1f093 So, please, create the rule and reply back if you have an issue with this. We’ll check to help you.
Regards
