how to get the "module" in the step settings pane

Hi,

I´m trying to rebuild an example for "Custom NI VeriStand Steps for NI TestStand". So far es I can see it I did the same things as in the examples. I draged a few stepst from the Insertion palette in the Main Sequence and now I want to specify the module but this button isn´t shown up in the Steps Settings pane.

I´m still a total beginner and have to work with Teststand for my bachelorwork. So please help me :)

Thanks
