Despite selection window set show layer only shows group number

Hi,
V5
when selecting an item that is duplicated and sits on two layers, one can right click the selection window and tick show layer,
however as both are grouped, all I see are a choice of group names, not the different layers they reside on.

What is the solution to this for grouped items ?

(another reason to have layer highlight to give an answer.)

@Steve1 Hold down ctrl-shift as you pick your grouped items. voila!
