Constraint Issues

Since the facebook groups are utter garbage (ask too many questions get banned etc) I guess I am back here where I have to wait 3 months and get no answer still I will try.

I have no constraint editor. It is that simple. I right click the capsule add constraint nothing to play with, I click on the disc things under the bones and nothing, right click, add constraint nothing can be done, I dunno what it is about constraints but I seem to not have any. Without constraints, I get what can only be described as an extremely stretchy explodey mesh when you hit play.

So what am I missing? I do not even have a constraint icon at the top. Hinge etc is also greyed out.
