Has something changed in recent updates to the GNS 530/430 V2 500 variant?

Last summer, I did a complete rebuild of my Windows 10 operating system. I reinstalled both P3D V4.5 HF2 and P3D V5.3 HF3. I installed my RealAir Duke B60 V2 in both with the latest RealityXP GNS 500 variant per the instructions and modifications provided by Bert PIeke. It was working in both versions of P3D. However, I did not fly the Duke again until last week. In the interim, I did multiple updates to keep Windows 10 up to the latest version.

After updating to the latest RXP GNS 530/430 V2 last week, I tried flying the Duke in P3D V5. I used a flightplan in the GNS that has an initial DTK of 251 degrees. With the flightplan loaded and activated and the instrument panel NAV/GPS on GPS, the course indicator on the HSI was pointed to 251 as expected but the popup on the course indicator said that it was set to 340. After taking off and using the heading bug set to 251 and the autopilot set to HDG to get near the desired GPS course, when I switched the autopilot to NAV, it flew the 340 course.

The same thing happens in the P3D V4.5 installed Duke.

Any idea of what changed?

This is the .ini I am using:

[GPS_500_1]
; is the master device if true.
