Prices not showing in the correct currency

Hi there,

For some strange reason the prices are not showing in the correct currency in Israel, we have 3 currency in our site at the moment.
US dollar for the US and Canada, ISR shekels for Israel and EURO for the rest of the world.
The Dollar and EURO it seems to work well but for Israel prices are showing in EURO.

Please advice us on how to fix this issue.
Many thanks,
Ran
