Hello @Kestutis,
We have not encountered this issue with our theme, so it appears to be an issue specific to your site. Could you please check it by activating the default WordPress Theme, such as Twenty Twenty-Three, to confirm that the issue is with our theme? If the issue persists with the default WordPress Theme, then it is not related to our theme and we suggest that you contact WooCommerce support again. Once they have fixed the issue with the default WordPress Theme, it should also be resolved with our theme.
Best Regards,
8Theme’s Team
