Element Selection window in Powerdraft select series 3 08 11 09 397

In the element selection window, it used to place the level of an element I clicked on, on top,

highlighted. This was very useful.

Then, suddenly, a few months ago, it stopped doing that. It now does nothing, when I

select an element.

How can I restore its previous behaviour?

What could have made it change?

thanks

I usually have the two left most items chosen.
