Why can't I add a new disk to an existing image?

For some reason the "Add" button is greyed out/not clickable. Im not sure what I am doing wrong? I have tried with the VM running, stopped and Shutdown all the same.

Im new to proxmox, so I apologise if this is a noob question.

you already have a sata:0 and (sata:1 for that matter). use the next id.
