Requisitions splitting into multiple POs due to lines having restricted purchasing categories

We've identified multiple situations in which requisitions are splitting into multiple purchase orders due to categories being either restricted or non-restricted.

From one requisition, there will be a PO created that includes the lines that have purchasing categories are not restricted. But if the REQ contains any lines with restricted categories, it will create a different PO from the same REQ for the lines that are restricted.

Is there any way that we can prevent this from happening?

See screenshot below for more reference.

Thanks,
