Member Formulas are vanished under Rules

Hello Everyone,

I have 30 member formulas for one account underBusiness  Rules in Admin but all of sudden i don't see them. But in UJFS i see the .LGX file for this account and i see all the formulas in .LGX file.

Did anybody face this problem?

Is there any easy way to get back all the formulas under member  formulas in Business rules.
