The two fields are usually (1) your Nostr profile's lud16, which is published publicly in your kind-0 metadata and is where other people's zaps go, and (2) the client's own wallet setting (NWC or a built-in wallet), which is what *you* pay zaps from. Receiving uses the profile field. Sending uses the wallet connection. They can be different wallets.
Quick self-check: paste your address into a browser as https://DOMAIN/.well-known/lnurlp/USER (so name@getalby.com becomes https://getalby.com/.well-known/lnurlp/name). If it returns JSON with a "callback", it can receive. Profiles cache on relays, so re-save the profile after changing lud16.
