Comment 20 for bug 1761606

Xubuntu 18.04.2
Two network icons appear at start up but not every time.
The 1st icon appears because Status Notifier plugin is enabled.
The 2nd icon appears because nm applet and network are included in Notification area and if I choose to be hidden only the arrow appears in panel instead of the 2nd icon.
Under 16.04 there was no problem ever.
xfce-panel -r solves the problem but not permanently.
Any idea on this issue?
