After further inspection, the only way I notice this is by importing this CSV:

The two waypoint items at the bottom ("missing 1", "missing 2") don't show up in the app's UI. If I change the cost to "0.0001" for those two items, they'll show up in the app. Those two rows I created manually. The other 3 rows were created by export from fuelio. But I don't see a difference between the ones I manually created and the ones exported from the app.
