postion scale and rotation greyed out and not working

I'm fixing a few prefabs that need to be scaled differently (the models are just a bit to small from the fbx) so I'm making a second prefab that has the correct scale and other scripts and things applied to it, however, while doing so all of a sudden I couldn't click on the Position, Transform, Rotation. I was, just five minutes ago but It suddenly stopped, I can hover over the x and drag it to the right number but obviously this is difficult if i want precise numbers. It's also not just the objects I was working on but all objects in scene can no longer be effected by the three transforms unless from another method.
