MarketFillter - Countries - NBA Games showing as GB not US?

[lordy]

Hi,

I'm trying to query Basketball events[7522] by country. Most of the US NBA games are showing up in GB?

Eg event 33251738 "New York Knicks @ Indiana Pacers" is returning a Country Code of GB, TimeZone is GMT?

Is this expected?
