Not Showing Liability & Prepayment account in Accounting tab in the supplier window.

HI,

We have 4 ledgers are US,UK,Singapore,India ledgers,

When we go to Accounting tab in supplier window  one ledger(UK ledger) is defaulting
where we set "Gl ledger name" profile option value as "India ledger"at site level.

Because of that it is not showing Liability account &prepayment account.
And when we select respectiv ledger like "Us ledger" and click on 'GO' in the accounting tab it is showing liability account & prepayment account.

And i checked in the operating untis also ,what ledger they have assigned?

Everthing seems to be fine.But why UK ledger is defaulting instead of  what we set at site level(India ledger)
