finder "arrange by kind"

i actually quite like the headers that separate document types when you set finder to arrange by kind. but invariably within a few hours these headers somehow get messed up and start actually displaying as folders themselves, which makes things very confusing.

relaunching finder fixes this, but it quickly gets old doing this several times a day. does anyone know of a more persistent fix? i'm already worrying that apple is going to become less aggressive addressing os bugs since it seems their priority has shifted to pushing paid upgrades on a yearly basis
