Sorry to hear that you are facing this issue. Can you please check layer options dialog?
From panel flyout open Layer Options and see if the thumnails for “Layers” “Groups” and “Objects” are selected and “Top Layer Only” is Not selected.
Also “Show Layers Only” check box should be deselected.
let me know if this solves your problem or not?
