Receivable system option does not show Receipt methods

Summary:

Missing LOV values for "Manage Receipt class and Methods" in Manage Receivable System options?

Content (required):

I have created Receipt Class and Receipt methods in FSM and assigned to BU1.

Then I go back to Manage receivable system options for BU1 and look for the value in Bank Account Receipt Methods associated with BU1. But this LOV is absolutely blank. Is there any connection missing and why would I not see any of the values populated in "Manage Receipt class and Methods" page?
