Love this mod, but it was bound to happen, I created TOO many, now I need to remove some.

They show up in the Layout Boxes Controller when I create them in includes/modules/sideboxes/custom but when I delete it from there the layout boxes controller still lists it by name, but is says MISSING.

I can delete the blank_sidebox.php, the blank_sidebox_defines.php, and the tpl_blank_sidebox.php BUT how does it get removed from the Layout Boxes Controler?

Thanks.
