So this is what was tripping me up. I went to my new alby account which didn't have any keys saved and put in my private key. Once I did this the "Remove current key" button appeared even though the account didn't have any keys saved. This made me worried that if I clicked it it would overwrite the keys in my other account. After your response I went ahead and clicked it anyway and was able to save the keys and it didn't overwrite the keys on my other account. Works great! I would recommend changing that button to say "Save keys" rather than "Remove current keys" if it is the first time that nostr keys are saved on that account.
