I did reinstall from 6.5.0 but that didn’t help. I was just able to get both presets to show by downloading and installing the ‘PRO’ version. Once I did that then both original and pro presets appeared. Strangely there were now duplicates but once I unselected and reselected the preset folder the duplicates went away.
All is well now but how strange this didn’t work from the master install.
