Woocommerce appearance adjustment issue

Hi there thanks for being here. I have a problem in running a multisite with Catch Base Pro. It is a shop-multisite with two sites in different languages. In the german one there is an issue with the appearance of either products, or categories, or both of them. Tried every option in the customizer, but there is always "categories and products" displayed in the categories page. In the free version this display works well but as this theme isn't complete woocommerce ready i bought the pro version. Is this a known issue, esp. one with the licence and running a multisite? Do i have to buy one more license to get it up and running well? Or are there some incompabilities with german sites known? Would like some help - i am completely perplexed Thanks
