I almost certainly created this problem myself when I was creating the profile for nostr:npub1lstr2kmdthkgfuzne8e4cn2nhr646x8jt25szdj7t4wr6xemtuuq3lczsj

I added the second profile to another account on Alby and it took me a moment to figure how to switch between them (i.e. you can't easily in the same browser).

Anyway, I think I have things cleaned up now and I'll keep an eye out for it. A backup/cache might be a helpful feature – even if just only the single previous list.
