Cart problem

[ctubu]

Virtuemart 3.4.5.10040
Joomla 3.9.4

I have a problem with cart popup window. It displays custom fields of related product an also doubles related product itself.
On attached picture product added in cart have 1 related product.

Can you give me some advice how to fix it.
Tried with different templates - Protostar, VMbeez, Beez, so I think it's Virtuemart issue.

Edit: custom fields belonged to product added in cart not related product.
