UK keyboard layout?

Hi, I have a problem with adding several keyboard layouts. Since my system language is UK, by default I have UK English layout, but whenever I try to add more layouts (System Settings > Keyboard > Layouts) the ones that have optional ones, like programmer/symbolic/qwerty/qwertz/etc. are okay to be added, but the UK one - since it doesn’t have any other options except its primary one - the “OK” button is greyed out. Is there any way to solve this issue? Thanks in advance.

P.S. tried LLM to assist me with this issue but to no avail.

This definitely seems like a KDE issue rather than a Bazzite one, the KDE community will probably be more helpful: https://discuss.kde.org/
