Blanket Purchase Agreement not available via Enter Requisition Line menu

Good morning, everyone.
I activated Responsive Self Service.
When I create a requisition from the catalog, I see the item associated with the Blanket and can complete the requisition without any problems.
However, if I create a requisition using the Enter Requisition Lines menu with the same item, I can't find the Blanket in the list of values.
I've collected some screenshots to illustrate the process.
Has anyone else experienced this issue?
Thank you.
