I can’t do the shortcut to roll a dice on beyond20

When I try to roll the dice from D&D beyond I can only roll it if I (as an example) click on my longsword and then go to the top right and click "beyond20", at first before I changed the settings if I hovered over "longsword" it would popup an icon in red, but now its grey and I can’t click it. Which setting do I have to enable/disable to fix this. I have tried looking over through the settings somewhere around five times.
