I selected the wrong one 
We have professional.
I built my workflow - I’m using Drill Down Source 2 and assigning a value to a new field called Lead Source. I was able to get the first workflow branch to fire with Drill Down 2 “starts with” user. But then it just passed by the next branches that were Drill Down 2 “contains” Slack, and so on skipping the other branches… Anything I could be missing there? Thank you SO much for your help!
