-1 gets set when the planner enters the Edit Tasks panel and change some other properties of the task and save the changes.
Planner has created tasks that have RateType = -1 and RateValue = -1. These tasks are using fix duration as opposed to fix rate or rate table. They planned the works orde, selected the Task Overview, then, spotted the RateValue = -1.
