Custom States do not show in triggers

I have created some new custom states on an image.  When I tried to add a trigger to reflect that state, the drop-down in the trigger did not show my custom states.  Is there an additional step, for the custom state to appear in the trigger? 

I am looking for a custom state of POS-2 or POS-3 in the trigger. 

 FYI:  The custom state does appear when I change the "Initial State".  Help please
