In your scheduling board overall profile, check if the propagation range is set to "SAPALL" and try rescheduling again.
If not check the activity "84205|||T" in the planned order and also what resource is it scheduled on.
I am guessing that this is the teardown activity and utilizes the same resource as the produce activity.
If it is a different resource then make sure that it has sufficient capacity to perform the "84205|||T" activity.
