Items I don't want in my shop

I made 3 designs with selected products and colors.
when I see my shop I see different objects with the design that I didn’t choose and with different colors.
Why appear objects that I didn’t selected, and they didn’t appeared in the list?

Hi there,
the products represent product groups. You can currently not design single items. We are currently working on a more refined filtering system, which should be introduced next year. However, I cannot give clear timeframe right now.

Did you set the default colour? That should in most cases help the colour issue. Secondly, you can refine the selection a bit already. Click on the three dots to filter product groups.
