That processor maintains state, it could be that you might have run it at one point.
You can verify by right clicking on the processor and going to "view state"
If there are values there then at one point it ran, and you probably want to clear the state.
To do so you can do that by clicking on "clear state" on the same place you viewed the state.
**** Make sure your processor is stopped.
Hope that helps.
