Spek Flatpak opens with locale warning

[NostalgiaRealm]

Using the Flatpak build of Spek 0.8.5 on Fedora KDE, I receive the following error every-time upon opening the application:

Spek Warning
Cannot set locale to language "".

@NostalgiaRealm What commands are you running to run Spek? The word AppImage is written in your issue, which is an entirely different application format from flatpak.

My apologies, I wrote this at nighttime last week and confused AppImage with Flatpak.
I am not running any commands to run Spek. But using flatpak run cc.spek.Spek yields the same results as above.
Spek was installed "Discover" on my distro. It is included in Flathub, which I have enabled on my Fedora distro running:
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
See: https://flathub.org/apps/cc.spek.Spek

Hope this helps!
