Allowed products / categories don't work for coupon VM 4.0.12 10777

[Kuubs]

The products are listed in the allowed category or in teh allowed products and i still get the message that the coupon code is invalid. If I remove the allowed products and categories it will apply the discount code. So in this calculation it goes wrong.

This is Joomla 3.10.11 and VirtueMart 4.0.12 10777
