Olga Presets In REAPER

Hi, I just downloaded the Olga demo and installed only the VST3 which I’m hosting in Reaper 6.19.
For some reason the preset menu in the plugin window is empty save for the default settings, and I can’t find a preset selector in the GUI proper.

I’ve trawled the interwebs including this forum looking for a solution but haven’t found one so I decided to sign up and share my concerns.
