Halion 6.15 VST presets not visible in HS(SE)3.15 after updates

Make sure you’re saving over the old presets in the right location. If you’re saving them as new presets or in a different location as the originals it will never update. For example if you created a preset in HSSE3 and then try to save it in HS6 it may save the preset in the HS6 folder instead of the HSSE3 folder causing there to be two completely different presets with the exact name.
