New Registry Population Data?

This afternoon I added some scans to my 1971 registry set. When I looked at my set just now, I see there are new fields in the listing, which seem to address variations of a given card and their populations relative to the card's overall population.
The odd part is, the "spec number populations" for all the cards I added scans for this afternoon are showing up as 0. Anyone understand this weirdness?

ETA: I wonder if they're locking everything out now to kick off the Pop 1/2 none-higher bonuses again.
White when there is a grade higher.
Grey when it is the top grade with others graded that high.
Yellow when it is a Pop 1 with none higher.
<< <i>That might explain an issue I just ran into. I went to add nine cards to my Larkin Master and not a single one worked. I had to request slots to be added or add to existing spec for every single one.

I had problems with my set yesterday also... I had to delete the items i just added and re add them and it all worked fine
