GTN 635Xi to HDX 'to' waypoint name

[rbr]

Hi folks,
Bottom right hand corner of the PFD has a square with magenta writing indicating that the NAV source being displayed is by the GTN. It currently shows the source, in my case 'GTN', next line is the distance to that waypoint. Below that is a space for the name of that waypoint. Last week the name of that waypoint was there, this week it has disappeared. Any thoughts would be appreciated.

What have you changed, or have you only calibrated your AoA?

Is the destination one in the GTN database, or is it one you've created yourself?

AoA calibration was done relatively recently.

All the waypoints were extracted from the GTN database. I don't think I have changed anything. ARINC settings match the Dynon 3rd party installation guide.
