Can't find enable/disable rigidbody component tick

I was making a RTS game, suddenly, all rigidbody components stopped having the tick to disable/able them. I am in Unity 2019.3.0f3.

Looks like a bug.
Consider upgrading your version (I think 2019.3.0f5 at this moment is out) and report it here : Unity QA - Bug Reporting - Unity
