Map charts not loading correctly.

Hello-

Does anyone know how to resolve these issues?

1. I'm trying to make a filled map by zip code in Illinois, but the zip codes are not generating properly. They are all clumped together. 

2. This chart also has an error- "We plotted 88% of the locations from your zipcode data with high confidence". All of the zip codes in this list are correct and should be mapped for Illinois.
