No need to open a second thread here.
Report it at bugs.kde.org (probably at the plasma-nm applet section)
Looks similar to 455180 – Plasma applet show as if connected to many wifi networks, except that old bug showed the network names at the additional connections this one does not.
Edit: just checked, did not notice it yesterday but I can confirm the same happening here:
nmcli connection show --activedoes only show one connection.
