Sub menu with list of my worlds I've created, the edit button is unselectable

On the main world menu screen the edit button is unselectable. Selecting the world I want to edit simply loads up the world. There is no way to highlight and select the world I want to edit. I tried typing the name of world in the open box at the top of the screen. I had the same result. The world loads up every time. I would rather not have to exit the complete game and reload the entire thing to edit my data pack in my existing world. It seems quite unnecessary when a button is staring me in the face. What am I doing wrong?
