Getting duplicated PR from same sale order item

[com_2018]

Dear Experts,

For example:

1. There is one sales order item( 37580 0020).

2.  Run MRP, it creates one new PR(1396629433)  then convert it PO(4500123122) by ME59.

3.  Created inbound delivery (1800003222) by VL31N

4.  Run MRP again, it created duplicated PR(1396629434).

5.  If I delete inbound delivery, after run MRP, it don't create new PR.

I don't know step 4.

Could you help me?

Best Regards,

Colin.
