@Nag 2019.2 deprecated those fields for ARM. They may no longer show up on new forms/transactions, those imo this is a bit sporadic. Strongly suggest you create custom fields for this purpose and use Revenue Recognition Field Mapping. If you do so, then you would be able to expect the behavior you describe.

Thank you !!!
