The native date created field for contacts shows up erratically in my views, some items it works, and some it doesn't.
The modified date field always displays however.
Additionally, there used to be a change log field on the bottom on contact creation, but now it's gone...!
Seems that some items that were created a while back show up, but some I did today don't, and I have no idea why some from a while back show and others don't!
