Panel's "Indicator Applet Complete" is corrupted; how to repair it ?

Uninformed fussing with the Panel has caused the Indicator Applet Complete to be filled with umpteen
WiFi indicators rather than Trisquel's basic set of indicators, including the WiFi (fan-shaped) indicator.
I've managed to set up an equivalent set of indicators for everything else that I prefer in the Panel,
but that WiFi indicator eludes me. It's a security issue, because unplugging the WiFi dongle freezes
the display more often than not.
One solution would be to copy & paste whatever settings file there is for the Panel from another
installation of Trisquel on the computer that has a correctly functioning Panel.
Right click on the panel and select "Reset panel".
You might want to write it down somewhere handy for future uninformed fussing:

It's eye-opening to see that I've had a similar problem with the Panel only three months ago ...
Alas, selecting Reset Panel from a Panel from which I've removed essentially everything
brings back the aforementioned umpteen instances of an icon representing an application that I
thought would aid in accessing or controlling WiFi.
It's this one Etiona installation which has acquired this flaw through my own actions. All the
other Etiona Panels on my three Lenovo T420's can be restored as lanun says.
Here's where I looked and what I've tried today:
(1) Looking at /dev/sdc3 (Data-II), an instance of the Panel which is set up OK:

(3) Search for libapplication.so reveals only binary files;

(5) After running "Reset Panel" on the almost-complete rebuilt Panel, still missing the WiFi indicator:

Which brought back the corrupted Panel, identical to that with which I'd started.
Solved ... by reinstalling Trisquel_9, which brings back the minimal necessary items in Panel.
Recently I've been using the Live DVD version of the install medium. Slow, very slow.
"Reset panel" should work now.
lanun's last comment isn't tongue-in-cheek ironic; when a Trisquel_9 reinstall finishes,
the three main items return to the Panel, including the WiFi indicator. That's our safe haven.
The other two are the sound/mute control and the clock.
