Many difficult on prebuilt website

My url http://www.hyperbros.com

After a couple of weeks of use, I still have a lot of problems with this template. Certainly also due to my inexperience, but I really don’t know where to start. I followed all the instructions in the “Newspaper Documentation” section, but there was nothing to be done. I also tried to use the prebuilt version of Gossip Pro, the aspect of which I really like, but starting from the home page, ending with the modules, when I set filters, I am promptly shown nothing. Not to mention the changes I make in the “Theme Panel”, almost nothing is automatically reflected on the site. In the AMP version then it continues to read “GOSSIP” in the header of the site … I’m really going crazy. And I’m wasting a lot of time. Can you take a look at my site and check it out for yourself? Thank you

Thanks for the reply.
I would like to point out only three of the strange behaviors.

1) In the center of the page there are three sections that I would like to be shown, I can with great difficulty filter only two of them (Europe and Regions). The first (Mondo) instead does not show it.

2) I don’t understand why in the “bottom” of the page I can’t see and therefore I can’t select the form for inserting the adSense code. I have tried to clear the codes everywhere but I keep seeing not one but two banners. I would like at least to see one.

3) In the right form I can’t show any category of those in the filters
