(I’ve moved this to casual as it isn’t a bug)
As of July last year, obscuring locations also obscures the date and time for the observation itself, and for IDs/comments. This was implemented to help strengthen obscuration and make it harder to interpolate true locations. You can read a good discussion about this here, plus more info here.
It’s not possible to decouple obscuration of the location and date; either both or neither are obscured.
(I’ve also hidden your screenshots since they showed obscured info)
