File Associations

Why does Bridge continue to associate with OLD versions of Adobe apps? All Photoshop associations are 2018. Even when it's not installed! And Illustrator is 2018 too. When I reset all associations to default it remains the same. And when I try and change associations the current programs are not available in the dropdown, even though sometimes older versions are! The only way is to navigate to the specific app in Explorer! This is ridiculous!
