How to manually edit PhAT shape box elems?

Hi, I’ve been stuck on this for a few hours now and I’m trying to manually set the value numbers on my bodies in the physics asset but not sure how to change it manually because it’s grey and can’t change the number. I’ve been able to change it before but not anymore. I don’t really want to scale it with the mouse. Any help is appreciated.

I don’t know, but working with Phat is a headache. A way to set values as you want will be ideal.
