Modifiers tabs won't work in fusion

Hi there,
So I'm working on a practice project. I went to use a tracker and the modifier tab worked fine. After that when I went to use a 2nd tracker and when I go to click on the modifier tab again it's all grayed out and won't do anything. It's like that for every node! How can I get those turned back on again?
Thanks
