You need to Merge both the loop in to a single loop.

I think,You cannot able do the frequency measurement and the pulse counter using the same counter paralley. So only you getting the errror like the specific resource is reserved because both the tasks are trying the use the same resources. So you need to clear your first task before your second task starts and again you need to create the task for your fist task after the completion of the second task.That is not happening in the DAQ Assistant.Check the attached VI.

Use two counters one for frequency measurement and another for pulse counter. Connect the same signal to the both counters.
