I found your problem. You're haven't linked your nostr npub with the wallet and it's using an npub generated from your wallet seed. You can see that the npub it has listed doesn't match your nostr npub.
You have go up to the top of settings and under the "Your nostr keys" section you have to select "use your nsec" and paste your nsec into the provided form. You should see your nostr npub replace the current npub linked to the wallet.
Then, toggle the "enable payment requests" on, and also turn on the "receive automatically" toggle.
Once you do all that and your correct npub is shown in the wallet settings, you'll need to update your nostr profile with the updated @npub.cash address which will also reflect your correct nostr npub.
Lemme know when you get that far.
