I try to search for a different pair.. JFK SFO and the app re-populates with TPE and BOS...
While I don't see the symptom of re-filling a particular city pair on the Book a flight screen overlaying my selection, that you reported, I was able to clear these fields completely by going to Android Settings, Apps, Fly Delta, Storage, and then select the Clear Data button. Essentially, this option appears to reset the app to "fresh install" condition. This is on Android 6.0.1.
