That's a conundrum @jock59 as the app markers i.e those orange dots should clear away to then show that you've dealt with unread notifications.
They are handy to see as they indicate awaiting information for you so personally I wouldn't turn them Off.
Try a soft reboot by turning your phone Off and then back On.
Perhaps perform a forum search to see if another member has posted similar issues to yours as the thread may hold a solution and or perform a Google Search.
One good generic troubleshooting tip is to clear the phone's cache files.
Clear your phone's System Cache Files by turning your phone Off and then from a set series of button presses go into the phone's System Files and clear the cache. No information is lost this way. You may need to insert your headphones or hook upto a computer with your data cable to get to this menu on the phone. https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/
I wish you all the best with this.
