Displaying values in a dropdown placed in a repeatable group from another repeatable group


I would like some help.

I am trying to create a project management app where the users can create employees and also create tasks and be able to assign the tasks to the created employees.

In a repeatable group I display the task created. The area where I am having issues is when I place a drop down in this repeatable group that show the name of the employee’s created.

Essentially the user should be able to assign the task to one of the employees.

See below the properties set for the drop down.
Note that the repeatable group is of Type “Active subtasks” and the emplyees are of type employees.

Please help!
