uninstall – Problems with notifications from already uninstalled gnome-shell extensions

I’m having a minor issue, but still a little annoying.
I recently uninstalled two extensions (“ubuntu-dock@ubuntu.com” and “ubuntu-appindicators@ubuntu.com”), but I keep getting notifications saying “Impossible to install -name of extension-“.
Thing is, I deleted basically everything concerning those extensions, rebooted every time and I kept this issue for the last 3 days, but I really would like to fix this.
I already did the following procedures:

I deleted the extensions from /usr/share/gnome-shell/extensions and from .local/share/gnome-shell/extensions.

Then I also deleted them via terminal, using gnome-extensions uninstall extesion@autor.

I also got a list of installed extensions with gsettings get org.gnome.shell enabled-extensions

At the end, I eve tried to install them again, and deleting them again with the same process.

Those processes successfully removed those extensions, yet the notifications appear at every end of booting.
Last thing: there is a third incriminated extension, colortint@matt.serverus.co.uk , which I also tried to uninstall and this one does not show notifications, but it keeps getting listed in gsettings get org.gnome.shell enabled-extensions, and that also bothers me.

Sorry for being very verbose. I hope someone might help me with this, I think it’s a weird problem.
