Some parts not showing !!!

They are listed in Outliner, with visibility on, selection on, render on, but they don’t show up in viewport and in render.
Also, the bones that control them don’t show up too (WTF!) while they are listed.
Any ideas???

EDIT: I tried to reset their transform location in case they were moved off viewport, to no avail.

You might want to post the file so someone can look at it…
