Screenshot of the field that has detected key combination

SUMMARY

I have mapped my Capslock to be an additional Ctrl from the System Settings. This works fine and everything usually works fine (it sometimes behaves weird when combined with Shift+Alt in Emacs).

Now, I went to create a keybinding in the System Settings, and I wanted the command to be triggered by Ctrl+Shift+e, so naturally I clicked on the "Input" button (which makes the System Settings to wait for a key combination input), and then pressed Capslock+shift+e, but it got registered as Ctrl+Shift+Capslock (and "e" is not even registered). It seems the Capslock key is detected twice, once before getting mapped and once after as Ctrl.

So the way I went around it was to use the actual Ctrl key during the key combination registration, and then from there after for daily use I use the Capslock

STEPS TO REPRODUCE
1. Map the Capslock to be a Ctrl from the System Settings
2. test it and make sure it is a Ctrl (e.g try Capslock+c and Capslock+v for copy-pasting)
3. go to System Settings > keyboard > Shortcuts
4. click on "+Add New" button give a command (e.g `notify-send 'aa'`) and press "+Add"
5. Click on the Input button to register a key combination, then press Capslock+Shift+e
6. see the registered value

OBSERVED RESULT

When I try to register the keys, Capslock is registered as Ctrl and Capslock simultaneously. (check the attached photo)

EXPECTED RESULT

I expect that Capslock be registered as Ctrl because I have mapped Capslock to be Ctrl from the settings.

I cannot reproduce this. Could you:
- Provide the version of the package xkeyboard-config (or xkb-data)?
- Provide the content of your ~/.config/kxkbrc? So we get the exact config you are using.
