reused password: app://com.agilebits.onepaassword?

Sometimes I do have to generate passwords independent of a particular site or url, bypassing the built-in 1Password workflow. That's because I can't trust the 1Password interface to get the password correctly inserted into the existing or new entry. That's just been my experience. 1password will offer a suggested password, but something whacky always seems to happen whether I click on that suggestion or highlight it and press Enter ( I still don't know how to reliably select it). So I sometimes generate a password manually, paste it into a sticky, and then paste it into 1Password. I don't like having to do this this, but I've gotten stung too many times by losing the new password. I think it happens more and more as sites offer js-driven (and sometimes modal) login windows that seem to clash with what 1Password expects. And then sometimes the browser 1Password plugin doesn't update very quickly, which is really annoying because if I try to log in, the site tells me the password is wrong. It's not a smooth experience.

Can you confirm with a tech how an entry with the url I gave you might be generated? And should those password entries be counted when 1Password checks for duplicate passwords? It doesn't make much sense to me.
