Those trusses you have created are objects if I am not wrong?
If those objects do not have a fill then the selection magnet will not work.
As the magnet is attracted to the fill of the element.
All you can do is to select the obvious nodes at the four corners of the truss or in the exact centre.
Creating a truss with the truss maker add-on does not create a fill it seems.
At least I can't get it to work.
It is a very old add-on.
