Without a shop link that will be very hard to give much feedback or advice on.
I realise you might not want to share the link, but if possible please do so along with any replication steps.
@Jason Yes, sorry. Actually you need a password to access the page, and an account to see the cart and checkout view. I would contact you by direct message. Hope that is okay for you? Sry for double comment, but forget to tag you.
