no, thats what happens when changing themes.
you select yuor layout of icons.
it then remains the same for THAT theme.
changing to a different theme, resets the icons, so you must then move to your desired layout and it will then remain like that for THAT theme.
i.e. change to each theme you are likely to use, change the icon layout to what you want.
then whenever changing themes, it will always be the same layout.
