If the guest is seeing lifetime points (total points earned till now) on iframe instead of the Available points in his account, it seems the checkbox for "Show total life time points on iFrame?" is checked under iframe configuration settings.
To resolve this issue, we need to enable "Show point balance on iFrame?" and disable the above checkbox.
If you don't have the access to these settings, please reach out to the Customer Support Manager to get the changes done or create a ticket with Punchh Support for the same.
