I'm learning how merges have changed - playing with dummy data and pushing things. I'm running into problems filtering the data file - I click the drop-down control and select one of the available entries - and nothing happens. The drop-down control stays black, showing nothing is going to happen! Or I filter successfully and then clicking the control and choosing (All) does not return the entire list. Sometimes closing the form letter without saving and opening again "fixes" things but not always. Is this quirky or is it just the phase of the moon?
