Thanks to KVR user Erisian for reporting this bug. There was a silly mistake in the installer which made it create the subdirectories for the presets twice, making them invisible to the plugin itself. This error has been fixed, so you can either uninstall it, download the updated installer (same link) and reinstall, or just move the presets from “C:\Users\[user name]\Documents\VST3 Presets\Kevin Breidenbach\FSA Shapeulator\Kevin Breidenbach\FSA Shapeulator” to just “C:\Users\[user name]\Documents\VST3 Presets\Kevin Breidenbach\FSA Shapeulator\”
Sorry for the inconvenience!
