Hi @julianrush,
Glad you reached out. You are on the right track, those fields are coming in directly from the payment gateway, and GiveWP doesn’t have a way to make changes like the ones you are looking for. You may want to consider giving this a go using the 3.0 beta plugin on a test or staging site only, and then sharing some feedback there as well. This has been a feature request for other payment gateways, so your feedback there would be a great way to share what you’d like to be able to do.
Outside of that, your best bet will be to reach out to the payment gateway. Some folks have had success with various gateways from that side of things, but that depends based on the gateway.
I’ll go ahead and mark this as resolved for now, but if you do have other questions about this you can send them along here and I’ll hop right back in.
