Gran Canaria SID KORA3B issue

[Tobias Nome 279]

I flied the KORA3B SID (rwy 21L) out of GCLP, when I saw an issue with the route drawing with the waypoint before "LPC". I deleted that waypoint, when I was in the air, and everything seemed fixed. But when I came to the 180* turn at "LPC" heading to "R063R", the plane continued straight ahead (NAV was activated). I swiched to HDG and aligned it with the route again, like this:

but when I swiched to NAV, the plane made a 360* turn, and then finally aligned correctly with the route:

here's a pic of the route page while flying the SID:

Hope you can figure this out
