VL10A Red difference highlighted and red light

[Fmll_]

IN vl10a I HAVE LINES highlighted in red with red lights and I have other lines highlighted in red with white or green lights, I know that the lines with red lights are when the delivery date has passed, but for those with red highlights, I want to know the reason and be able to group order items that are highlighted in red.

PS : i do not have access to spro 

thanks
