hidden revit link that does not want to appear

[mir]

Bye!
I have an object (actually in rvt link) that appeared without problems ... then I changed it and now in the confederation I can not make it appear. and when I press on the bulb the object appears in burgundy but it does not let me appear ... that may be?
grazie

it would be to see how the "display settings" of the links are set. difficult to give a solution with these few info

I try to see those... but the previous file I edited didn't give me this problem. and, as you can imagine, if I open the link I see everything correctly
