LNAV issue - RNAV Z RWY 15 into YPCC

[rare solstice]

Flying into YPCC tonight, on final for the RNAV RWY15, there was a hook drawn on the ND for an 180 degree turn at the waypoint PCCNF. I was hoping it was just a visual bug, but the AP did try to make the turn before I switched it into TRK mode.

I’m not sure if it’s a navdata issue or not. I’m using Navigraph navdata, but wanted to report it here just in case.

Full flight route is pasted below and I'm adding screenshots for reference.

Transition/VIA was PCCNE

Just loaded the plan into the default a320 (🤮) and went through plan mode and I don't see a 180

Delete PCCNM and it will be fine

Limitation of the old flight plan system... it always inserts the runway as MAP after the actual MAP if it's not a runway
