Garmin G3000/5000 Issues and Support

I have an issue perhaps someone can assist. I understand in the G5000 about the course reversal line, which is seen in my screen capture, but last time time i checked, a flight from New Jersey to Los Angeles is not over 4000 miles and should not take 10+ hours to complete. Anyone with similar issue or can show me something I am doing wrong. Also, when setting up my Vnav works perfect for about 2 minutes each flight. The FLC button then disengages itself and i have to push it a 2nd time. Again, anyone with this issue? It is every flight regardless of altitude limits etc etc. Thanks for any help
