he should take a look, if he´s still listed in his old team (at lfsw).
the "bug" in lfsw is, you can be listed in multiple teams and it
looks like, it delievers always the oldest one.
tell him to go to lfsw, go to his old team, look if he´s still in and
if so (what i guess) he can manually remove himself over the
new button "remove...."
