Custom place location will not populate with observations

General
1

I am working on a project where I am comparing two cities for biodiversity. In doing this, I have created two custom places in google maps and downloaded them as KML’s. I then created two places in iNaturalist and used these KML files for the boundaries. When I look up these places then, it says there are no observations in these locations. When i try to create a project with these places as constraints on observations, still no observations. I was wondering what I might be missing?

Google Drive Folder with KML files:

Places on iNaturalist:
-Detroit:
https://www.inaturalist.org/observations?place_id=177467

-Ann Arbor:
https://www.inaturalist.org/observations?place_id=177465

It takes time to populate places, check links now, they show observations, probably will show even more over time.

Place editing is one of the biggest iNat slowdowns, so expect it to take awhile. Also, we now have 2 places for Ann Arbor. If they can be merged that would be ideal.
