Hi @basvweb!
It looks like this could be happening due to a conflict with your theme or with another plugin.
To be sure, please perform a conflict test by temporarily switching your theme back to Storefront, disabling all plugins except WooCommerce, and then check again if the issue persists. If that solves it, then re-enable all plugins one-by-one, until you find the one creating the conflict.
If you cannot perform a conflict test on your live site, we recommend creating a staging site using the WP Staging plugin.
You can find a more detailed explanation on how to do a conflict test here: https://docs.woocommerce.com/document/how-to-test-for-conflicts/.
Let us know how that goes for you!
Hi there,
We haven’t heard back from you in a while, so I’m going to mark this as resolved – we’ll be here if and/or when you are ready to continue.
