PO header DFFs not appearing on POs generated from planning or Drop ship

We have a requirement to communicate Purchase Order to supplier through integration, as part of which we have context based DFFs enabled at PO header which are also being communicated to Supplier.

For POs created manually, we can view the context DFFs getting defaulted which also reflecting DFFs under that context under PO header> additional information, however for POs generated from planning or drop ship, these DFFs are not reflecting, context is just greyed out, but if we edit the PO and select the context, we are able to see the DFF values.

This impacts critical fields that are being passed over to supplier for the POs generated in Fusion. Any pointers or inputs on this is really helpful
