Problem with task

Hello,
I have problem with making a simulation.
I have got a message: One or more of the NORMAL tasks are unchecked in the task selection panel when performing a (re)start.

I use robot YuMi with options: multimove coordinated and also conveyor tracking.
I added task for conveyor to robot controller and activated mechanical unit CNV.

I want only make a program using only one hand of robot, the rest (left robot hand and conveyor have no program).
In the simulation setup I make simulation only for that hand I set.

I have no idea how to fix it or what I doing wrong.
I would be grateful for any help.

Not exactly sure what your issue is but I will make a guess. If the controller wants to have tasks for the other hand and conveyor, which you don’t need. Make Dummy tasks for them which simply do nothing. WaitUntil FALSE; is an infinite wait, but those tasks will still be executing.
