I have what appears to be an ordinary login in 1Password, with a title, username, password, and two URLs. I can see it under "Logins" in the application, and I've favorited it and it shows up there, again in the application. However, it doesn't show up in the mini or browser extension. I haven't done an exhaustive analysis, but this is the only login that I've noticed this happening with (and, of course, it's a login I use frequently, with an extra-long password). I've tried duplicating it in the application; the duplicate doesn't show up in mini or browser extension, either.
