Why Does the "Supplier Item" Field Persist When Using 'Create Another Request' in a Smart Form?

When creating a requisition using a Smart Form, after adding the first line and selecting 'Create Another Request', the "Supplier Item" field persists in the new request. Since this field is specific to the individual line and not general supplier information, it doesn’t seem appropriate for it to carry over.

Is this expected behavior, or is there a way to prevent the "Supplier Item" field from being retained in subsequent requests?
