Garuda Live USB changed my fedora install

Hi All,
I was checking Garuda on a live usb session, tried to launch Gparted, got an error message and rebooted to try out with another usb stick.
When i booted back to fedora in order to do so, my display name was renamed from fedora to garuda-gnome.

Any clues on why that happened or how can i fix it?

It can be assumed that gparted has nothing to do with it.
Why would the live ISO change anything if you didn't start the installation?

Maybe you could explain "where" this is displayed.
