An incomplete stop is a stop that consists of several tasks, of which some of them are complete, but others are canceled.
In this case, the report will appear as incomplete, since there are one or more tasks that have not been completed.
In this case, it is recommended that you move that stop to another planso that it can finally be completed.
From the menu (the three dots in the header), click on the move stop option. In this way, you can move the incomplete or canceled stop to another plan or even store it in "Unassigned stops page" (in case you don't want to move it to a specific plan yet).
