Bug with Bing Maps for defined USA counties

Hello together,

I would like to visualize a kind of heatmap for the unemployment rate of all US states and counties.

Source for US Unemployment Rate States: https://www.bls.gov/web/laus/laumstrk.htm

Source for US Unemployment Rate Counties (just the latest): https://www.bls.gov/web/metro/laucntycur14.txt

With the states everything is fine, like this: (data category = "state or province")

But with the counties it looks like this: (data category = "county", all counties named like "Anderson County, SC"

 I've already tried to describe the county rows like this: "<County>, County, <State Code>", but there's no other result.

Could help me someone or is this a Bug with Bing/Microsoft?

Thank you very much!

BG,

Sven
