Cessna 404 HSI glidepath inop on RNAV approaches

ISSUE DESCRIPTION

Description of the issue:
When an RNAV approach with vertical guidance is loaded/activated, the HSI doesn’t have a glidepath indication, despite the “LPV” annunciation showing up on the GNS530. The glidepath shows up properly on the #2 OBS when an approach is loaded into the GNS430, and I’ve tested other six pack airplanes on the same approaches (their glidepath indications work properly), which confirms that the issue is confined to this specific aircraft.

When the #1 NAV is tuned into an ILS, the glidepath works properly on the HSI.

If applicable, which aircraft is experiencing this issue:
Cessna 404 Titan
