Quote cart problem

Hi

Quote Cart problem in both of my sites:
ekoliikelahjatukku.fi/ekologiset-liikela...ngaton-paistomittari and heijastintukku.fi/heijastimet/pehmoheija...moheijastin-nelioe-2

I use:
Joomla 3.9.15
Eshop 3.3.0
Fashion Template 2.1

1. add product to quote cart
2. continue shopping (Jatka ostoksia)
3. push quote cart and delete product from X button
4. pop up window comes with error message

BR,

Jani

Dear Jani,
