Mcdu dir

[PLATOE]

Have a look at this post I created today. I had a reply from one of the FBW guys & he helped to clarify my similar problem.

FBW A320NX Direct to function deletes entire Flightplan

In the last few flights I’ve done, as soon as I use the DIR function to go directly to another waypoint, the entire flight plan gets deleted. A lot of the waypoints are still visible, but the is no line connecting them & the plane just flies straight & level. Anybody else having this problem?
