TDS GTN no VDI indication on LPV approach

[eMko]

Hi, when I tried to use TDS GTN 750+650 (and DFC autopilot) VDI wasn't shown during an LPV approach (when I tested it with the X-Plane default GNS it was shown). Has anyone noticed this as well? Is there something between Entegra avionics and TDS GTN or do you think it could be an error on my side?

I'd reach out to TDS and advise the specific approach being used.
