Please check product Laila in Dutch. There you can see the difference between Storefront and Woodmart. It works fine on Storefront, not on Woodmart. I have added a screenshot to show it.
Hello,
Sorry for our late response.
It seems like it is not cache related. We have disabled and removed Litespeed and Cloudflare cache, but result is the same. In default (or any other) theme it works fine. In Woodmart it remains a problem.
