Printing the labels with Transfer Quantities works only in Draft state. It creates a blank PDF when in Ready or Done state. It only works if I choose Custom ​Quantity.
I tried reinstalling the stock module but still creates a blank PDF.
Is there a way to solve it or at least debug the problem?

Edited: Here is my odoo log output when printing the labels in Custom Quantity
