Why does the Concurrent Execution pane say "ignored" next to Tasks and Mapping?

I am trying to deploy my model to a multicore processor target. When I open the Concurrent Execution pane, it says "ignored" next to the "Tasks and Mapping" option. Why does that appear?

That appears because you have not checked the box labeled "Enable explicit model partitioning for concurrent behavior":

For more information on concurrent execution, access the relevant documentation by executing the following command in the MATLAB R2020b command window:
