Unable to select subledger application on Attribute Defaulting Rules form

Content (please ensure you mask any confidential information):

When trying to implement the Accounting Hub Ledger Derivation feature from release 25C, I am unable to select my subledger application on the Attribute Defaulting Rules form, as it does not appear in the Entity LOV at all. I have ensured that flexible configuration of accounting hub is enabled, the ORA_ERP_CONTROLLED_CONFIG lookup is set up as required, and the subledger application is even able to process and account for transactions. Moreover, I can also see other applications in the LOV.
