I think I got the problem, only need a solution. When I enable sidebar position in Shop page Layout, it enables the sidebar in the categories and vendor store page together. I want the sidebar enabled in de product categorie page (general shop page) and disabled in the vendor store page (Dokan). Is that possible?

1) I already removed the sidebar and its content, but the space where the sidebar was positioned is staying blank and the store pages therefore are not centered: https://ibb.co/DKSZQ0L
