If I understand this correctly it seems there is a bug where the default fill background pen affects the fill for schedules in layouts - why I don't know.
Go to your plan and look at the default setting for the fill background pen.
If it shows as a coloured wheel then this is the problem change it to a valid pen colour - probably the transparent pen (pen 0).
Then update the schedules on your layouts.
