Often, to not say always, when I create a new flight and enter a custom name for the flight, the name reverts back to the default one after a while. It does this regardless of if I create the flight in the windows app or in the android app. I need to enter my custom name a couple of times before it gets saved properly. I cannot tell when it reverts back, just that all of a sudden I see the name changed back to default.
This bug has been around for a long time.
It seems that every time I modify the flight, with another SID/STAR the name of the flight changes to the default naming convention.
