8.10.4 shows warning on all LastPass imported items

Hello JohnInCA,

Thanks for your message.

I understand that you changed your important passwords before moving over to 1Password. As Watchtower is seeing this as an exported item, it won't recognize the password was previously changed. The banners will remain on items until either the password is updated within 1Password or you ignore that banner. It's not possible to globally remove the banner from items.

With regard to the tags on imported items, if you right-click that tag > Delete Tag from the left sidebar, it will remove that tag from all associated items:
