I am totally confused here. Our locale setting list United States as the only locale (that's what we want). However, the default currency is empty. When I run a test to see available currencies and try to add a new locale, there are no available currencies to select from the dropdown. Am I missing something here?

Our site has been running for over 2 months without problems. The reason why I am messing with this at this point is because I am importing new products and the excel import is creating duplicate empty categories. Referring to the manual, this happens when the template is not correct (fixed) or when there are multiple locales (we have only US).

Can anybody please help? I am using MS 9.3.0.0
