Fitness Age and resting heartrate - calculation is wrong

I've got the problem, that the garmin calculates my fitness age five years too high, because my "resting HR" is always the average heartrate of my last ride! I added the resting HR manually in Garmin Connect (and it was transferred to the 1040) but after my ride today, it still said: "your resting heartrate is 132".

Second problem - in the app I set my "weekly intensity goal" to 350 - but the garmin still says "your goal is 150"! How can I change it?

Thank you.

Stefan
