How to submit a correction to Placekey?

I found an error in the place data, and I’d like to know how to go about fixing it. These two addresses result in the same Placekey data:

Gristedes
225 8th Ave, W 21th St
New York, NY 10011

Gristedes
225 9th Ave, W 24th St
New York, NY 10011

However, the following results in a different placekey:
225 9th Ave, W 24th St
New York, NY 10011

Also, see the following screenshots:

It appears adding the POI Gristedes throws off the location result. How can I submit a correction?
