When using a quality Requester Chest (in my case a "rare" one), the icon for the quality of the requester chest will be on top of the icon for the quality of the requested items (if requesting more than 2 items).
In my specific case my rare requester chest is requesting uncommon concrete, uncommon steel and uncommon processing units.
When looking at the chest it looks as if it is a "normal quality" requester chest requesting uncommon concrete, uncommon steel and rare processing units.
