8.10.4 shows warning on all LastPass imported items

I was excited to see the solution from @tanglewood and tried a slightly modified approach that also worked. In the Windows desktop app, I renamed the LastPass tag rather than deleting it. Same result. All those warnings gone. The renamed tag still has the same items included as the LastPass import on xxx tag, so I'll probably delete the other. Just an experiment. Thanks, @tanglewood !!!

Another suggestion/request for 1Password from me, a new convert: I am often interested in the count of how many items are associated with a tag, a vault, etc. The count is inconveniently available at the bottom of the list, which is often very long. Why not put it at the top of the list, or even in parentheses next to the tag name, vault name, etc., like many other programs (especially email clients) do? One way or another, make the count conveniently visible without scrolling. I suppose I'll add this suggestion as a separate topic, but it was on my mind during this lastpass cleanup process.
