My unit appears to be losing custom location and past flight records each time it is powered off. I first noticed it after updating to 5.14. Updated to 5.15 today and still get the same result. When I ask it to display past flights, I don't get the standard list of flights, but instead I get an error window stating that "An unhandled error has occurred". When looking for custom locations, it tells me that there are no custom locations. Any thoughts about what might be up with that?
