1. KB4507419 came in twice. Any idea why? Normal M$ mess? 2. KB4512192 came in and installed on 9/6. Then on 9/8 it was listed to download. So I did. It immediately told me "you're up to date". Great. Except today, third time now, it was in the download list. I figured it'll tell me I'm up to date. But no, it actually installed. Please see my screenie. What's going on? Has anyone seen such duplications? And what might 2019-06B indicate for 1809, up top in the picture?
