Garmin homeport route not visiable in gps.

Hello.

I have made a route in garmin homeport to my garmin gps 720s.

Dont know if I have saved it wrong ,but it does not show full route length in the gps after transfer by sd-card.

It show distant 0mil and when I choose it as a route it, it does not make the colored path on screen.

What am I doing wrong or missing?
