reference sets - object selection problem from nx6 onwards

[matfio]

Hello, everyone.
I've got a little bit on the reference set that I've been carrying since nx6.
I try to explain.
I create a new reference set with name "model" I add an object. It's okay.
I add surfaces, solids continuously for various reasons and I find that the reference set "model" is full of objects. I try to uncheck them to have only the basic solid and give me as a result 1 selected entity.
apparently it is correct inside the component but when I go in the mode together I find that more than one object is displayed. What to do? cancel and recreate the reference set is not as correct as a procedure but I am forced because there is no way to settle.
I remember that previous versions (from nx5) had the following options: add objects, remove objects, edit objects and when I happened the problem of selection the only possibility I had to solve it was edit objects, select all, invert selection and finally select the desired object again.
I press that in the environment together there are saying methods to view the interested object but I am a free professional and I must always adapt to the ways and methods of working of my customers.
Can someone explain to me if there's a solution for version nx6 onwards?

provided that I am not very clear about the problem you have on the reference set (if you have only one item selected, in assembly you only see that), but if you want to uncheck everything, even in nx6-7-7.5 there are the buttons "select all" and "deselect all" in the toolbar selection.
Bye.

(if you have only one selected object, in assembly you only see that one.

It should be like this, but it doesn't always do it, it happens to me.
inside the component the selection is correct (type 1 object selected) but not together.
