Hello Predrag,

Thank you for reaching out to us.

I suggest you swap the german market plugin for the plugin woocommerce Germanized (https://en-gb.wordpress.org/plugins/woocommerce-germanized/). Apparently, this is a problem of incompatibility between them.

Let us know if it helps, please.

If you need some further assistance, please don't hesitate to contact us.

Have a nice day!

Dear Predrag,
