CH47F Chinook way points issue

Hi everyone,

I have been flying the Chinook for a while, and I need your help with navigation management.

I usually cold start the helicopter, mark my current farp location to navigate back to it, add this mark to the flight plan, then manually enter the remainder of way points. I have noticed there is an additional way point called FR that shows up the on my FLPN, even though I never added it.

Everything works well when I'm flying my original flight plan, but things get messy on my way back. I simply can't find the farp mark / way point anymore??

I have no idea how it why it disappears from my flight plan! Is it a bug, or Am I doing something wrong?

Please advise!

Thanks
