Ok thanks. That makes sense then.
Yeah, as long as you could deselect a col it would be great.
Just to confirm I mean a single metabox in a field group was temporarily set with a column, and there was no way to remove it so I set it to 12. After that all meta boxes in that field group have labels on top.
It's just cosmetic, so not urgent, but looking forward to the ability to delselect the col.
Thanks again for the help!
