After creating a constraint profile if the constraint types are switched they will not be saved.

If you convert the constraints when you have a profile active and then switch to a new profile and back again the converted constraints will revert back to whatever they were when the profile was created.

This is strange as if you convert the constraints and hit simulate they will simulate with the new constraint type.
