Hi,
So, from what I can see on your page, Broodvariaties is actually the name of a product which you're using as an option of your main product "Gezond".
So the "Sandwitch ..." text comes either from the name you set in each variant of the Broodvariaties product, or the values of the characteristic added to the Broodvariaties product.
So check the names of the variants of the Broodvariaties product, and then check the values of the characteristic in Products>Characteristics.
If that doesn't help, please provide screenshots of these so that we can get a better grasp of the situation in your backend.
