Impossible to save and use

I purchased the pro version. I have installed and deleted the plugin several times to try to solve the problem, I have also totally deleted the cache but nothing to do. It is not possible to save the changes made in the Automatic Setting section. Every time I select Category Based, I find myself pre-selected of the categories produced in a split group but going to remove the tick and clicking on save changes reloads the page but my changes are not saved. We return to the previous situation. How can I solve it? Are you dragging data from a previous configuration? Thanks.
