Hi I would like to know if this is a config error or an Odoo error

On odoo 12 when I have a reordering rule for a product and run the scheduler it creates a transfer where you can see the source document as the name of the procurement rule

But if I have 2 product that have procurement rules to use and run the scheduler it doesn’t show the source document

I don't know why this happen and what the correct way to solve it.

Thank you in advance
