You likely somehow added a second "user" repository for Flathub. By default, if you run flatpak remotes it should just return flathub system. However, you can set it up both as a system and a user repo. If you install something with flatpak using the --user or -u flag it creates a new repo. Solseek goes by the default setup for Solus which is the system repo.
If you want to fix this, no data will be lost; you can do the following...
flatpak list --app
Make note of apps / IDs in that say "user" under Installation.
You can then uninstall them all using
flatpak uninstall --user --all
flatpak uninstall --unused
Again this will not delete the data.
Then remove the user repo
flatpak remote-delete --user flathub
Now you can reinstall the apps that were installed as user. Your data and config will still be there.
