command subtitles component, not working properly

[skia51]

Bye to all,
I have a problem with the substitute component command, in practice I follow this sequence of operations.
I open the main aid, save it as a copy and open it, I take the sub-committee that interests me, also this I save it as a copy and open it, within this together I take the part that interests me, also this save as a copy and open it, I modify and close it. Now I am in the background, I try to support the part I have modified, but in the command I see the assemblies that I opened before and I can't exclude them, so besides the part that I have modified, in my subset I find all the open assemblies.
I hope I explained.
Is there something wrong with this procedure?
I attach the command image in which you see the axioms that solidworks wants to replace, and that I can't delete.

browse and go fishing the part.
those you see are the files you opened in the current session

Hello Masses,
when I click on browse and choose the file to replace, this adds to those present.
I also noticed that this behavior does it when I save the assemblies as a copy.
if I do not do this, even if the current session includes more open files, the selection window turns out empty and I can add only part that interest me.

Right. select it and confirm it.
those you see are the solid files you propose, it is not that you replace a file only with 4 different.

is not that it replaces you a file only with 4 different.

thanks massive,
I have to check, since if I do ok inserts all the details that are described in the window.
Now as I have written it is a behavior that never always appears, as soon as the occasion returns, I will try to select only what I need

It seems very strange because a component can only be replaced by another component. to me in fact does not allow to select more than one

Hello Massive
I checked, if I direct the ok, solid inserts all the components I find written in the box, but I can effectively select one and so solidworks replaces only one component.
the strange behavior is that I do not always find details or assemblies already proposed by the software, other times, while having more open files at the same time, the second box is empty and then I choose what I have to replace.

Hello Massive
thanks for the help
