FMS Waypoint error

[Stefan Schweizer]

Once insert a direct to with ABEAM points, I noticed frequently a total FMS waypoint mixup.

The T-P draws a direct line to the destination airport and all Waypoint predictions has negative values, see image.

The only way to get out of this is to reload the FPL into the Secondary FPL and then swap to active. Still you have these corrupted waypoints, but after a direct to a fix, the predictions restore to normal values.
