Brave notifications disappears in High Sierra desktop notifications

Hi i am having problemas with receiving the brave browser notifications into my mac notifications center. The notifications works but after few minutes disappears! Suddenly they were appearing more and more the same notifications so i went to the permissions_ notifications and i have seen several different pages from tradingview ( https://es.tradingview.com, https://fr.tradingview.com… so i have left just the https://tradingview.com --> cause the same notifications were appearing in notifications center… after i have left just original web page there are no more notifications in my mac notifications center. Very annoying …
