Not values in entity reference field

Hi,

Apologies if that is a duplicate or related to inline entity form. Im not getting any values in the entity reference field.
The setup is: I have a product display which have an inline entity form field (single value) referenced to product. Also in product type I have a entity reference field which is node reference. When i try to add a product then the entity reference field list the values. But when I try to add the product trough product display with inline entity form then the entity reference doesnt have any values. Including images just for a better understanding. Is it something what Im missing or a bug?
Thanks in advance
