Hi Tuan,
If I disable both of the setting in the configuration like so:
It will still show the Billing record.
I have a suggestion, I think you can easily implement it. Can you add a filter for Billing and Members? That's the first thing I was looking for when I looked at the Registration Management since I enabled all of the settings in the Configuration so I see everything. Also, you can hide Billing and Members filter depending on which configuration setting was enabled.
Seeing the billing info as a record / row is kind of confusing at first since billing is not considered as registrant. So I guess adding a filter would make sense or moving the billing info into a row column instead of as a separate row.
Thanks,
Jackson
