After choosing to "download originals to this mac" photos do not show up in Photos library master file and I can't extract them to move them. Please help!

Hi all!

I took advice of another thread on here for transferring photos in bulk out of Photos Library to another photo management program. To do that I chose to "Download originals to this Mac" in iCloud settings so that all my photo from phones and iPads and what not would download into Photos Library.

When I am in the Photos app I can see that it has downloaded originals.

Yet, when I then go into Photos Library --> Show Package Contents --> Master file, where all originals should be stored and easily extractable, I only see some of the photos that were downloaded and stored a long time ago, but none of the new photos I downloaded from the iCloud!

Any ideas of where they are or may have gone or how I can make them visible?

I double-checked that I am using the right Photos Library, but weirdly the size of that file itself also has not changed since Photos said it's downloaded the originals...

I need to move several years of photos from iCloud to the Lightroom and I believe based on what other users have suggested this is the easiest way to move them with dates in tact, so I really need to figure out why they are not showing up...

Thanks a lot for your help!!!
