The Encoder Page gives the user access to 8 individually assignable Encoders - and simple layout tools for saving configurations. Encoder Assignments are stored and parsed by oscRFR - so if you assign an Encoder to be "Magenta" it will always control "Magenta" no matter what type of light is chosen.
Both of these options will wipe out any stored page layouts you may have.
We know this is annoying - but it's the best procedure we have for right now.
