Task Logic Tutorial 1.3 Task Executor Error

I'm following the Task Logic Tutorial 1.3 (Tasks Using Lists) and keep getting the errors below. I've attempted to build the model twice now but it is still not working. The flowitems seem to arrive in queue fine and get put on the list, but the processor is unable to load item from the queue. The model is uploaded below.

time: 0.000000 exception: Error: Bad Task Executer/Task Sequence reference in starting Task Executer activity Processors Pull Items From List/Load Item from Queue in process flow "ListLogic"

time: 5.000000 exception: Error: Bad Task Executer/Task Sequence reference in starting Task Executer activity Processors Pull Items From List/Load Item from Queue in process flow "ListLogic"

@precilla.t2,

You did things correctly, but it appears that something happened with the activities that interfered with their functionality. This could have been dragging something or accidentally highlighting and editing something in the Process Flow and is a buggy, but uncommon occurrence.

I was able to fix this error by deleting the "Create Load Unload" and "Load Item from Queue" activities and then adding the logic again. I'm not sure which value was causing the error, but this fixed it for me. Let me know if you have any further issues.
