'Edit User scales' function blurred out on Harmonic pitch

    Howdy


    Trying to edit some custom scales, but the two 'edit user scales' buttons are effectively greyed/blurred out. Is there something im missing or need to enable?

    Maybe you'll have to select "User Scale" with the knobs in the bottom.
    Those "Edit User Scale" are greyed if you choose something like +3rd for example.
    Just turn one of this knobs to the right and you'll see it juste after + 3 Oct.


    Hope I made myself clear...
