Does this even make sense to you? I acknowledge I am not an experienced Linux user yet, but this seems most weird to me; why would KDE Plasma offer me to update GNOME?
For context, I am using Debian 13 Stable, which I installed just with KDE Plasma - so I’m not running more than one DE, nor did I install more than this.
All the “App Store” apps like Discover are merely frontends for your system’s underlying package manager (
aptfor Debian and derivatives,dnffor Fedora and its derivatives).The underlying package manager does the updating of packages: if you’ve installed it through the package manager (which is usually most stuff on an install) - it’ll get updated.
Discover just gives you a nice, user-friendly way of interfacing with the package manager(s) on your system so you don’t need to bother with the CLI if you don’t want to (that’s what “frontend” means - a nice, friendly UI for underlying services).
And yes, you can have multiple - for example
aptand Flatpak. Discover and friends should update all.Gnome Platform aside (as most comments suggest, probably a flatpak dependency), Discover updates everything installed through your package managers. It does not differentiate between packages. This is why it also updates GNOME Packages if they are installed
Don’t worry, I get KDE updates in GNOME.

🤣
It’s not the entire DE. You have application installed made for Gnome and that is one of its dependencies.
