See the attached screenshot please.
I have several Plasma widgets from KDE Store installed on my system, but the Widget Explorer only lists 2 of them when its "Uninstallable" filter is selected.
When I want to uninstall any Plasma widget not listed in the Widget Explorer, I need to open "Download new plasma widgets" window and select "Installed" radio button. 

1. install some Plasma widgets from KDE Store
2. open the Widget Explorer and select "Uninstallable" filter on top

Widget Explorer should list all widgets installed from KDE Sore when its "Uninstallable" filter is selected.

Operating System: Arch Linux 
KDE Plasma Version: 5.19.0

It works for me. Can you please try if you can remove these addons from within the KNS dialog? It might be possible that they are "orphaned" entries in the KNS config file (~/.local/share/knewstuff3/plasmoids.knsregistry).

I have uninstalled all widgets via Widgets Explorer, they are no longer present in the Widget Explorer but they are still marked as installed in GHNS window
and when I click on their "Uninstall" buttons they bizarrely change to "Installing" and get stuck in such state. Then I installed all the widgets shown in my screenshot and now they are all listed when "Uninstallable" filter of the Widget Explorer is selected.

Is it possible that you have removed those entries using the "Delete" icon? There might also be a problem with the KNS kpackage support, should be an easy fix :)

Fix undetected KPackage installation

This was the last occurrence that didn't get ported/detected.
Because of that the updating did not work and uninstalling
an entry using the "Widget Explorer" did not work.
