B2C E Commerce Registration screen is not defaulting the country name

Hi

We have implemented B2B and B2C E Commerce CRM5.0 ISA solution.

In the B2C Registration screen we are facing issue as the country name has to be defaulted to United Kingdom but its blank because of which Registration RFC is not allowing any registrations.

There is ADRC table which is maintained correctly which COUNTRY GB.

Could you please help tracing from where country is getting populated in front end?

Thanks
