SUMMARY
I recently bought a HP Pavilion 300 keyboard which has some keyboard shortcuts which under the hood map to 
- Meta+Alt+Shift+Touchpad Toggle
- Meta+Shift+Touchpad Toggle
- Meta+Touchpad Toggle
- Meta+Ctrl+Touchpad Toggle

These mappings are compared with evtest

I am having some trouble assigning these keys via the systemsettings UI. 
Meta+Shift+Touchpad Toggle is detected as Meta+Touchpad Toggle, and
Meta+Alt+Shift+Touchpad Toggle is detected as Meta+Alt+Touchpad Toggle

The end result is that assigning these keys via the UI does not result in working keyboard shortcuts.

If I assign these keys manually via .config/kglobalshortcutsrc and reboot, then everything works as expected. So the shortcuts work, it is just the assigning via the UI that is broken.

STEPS TO REPRODUCE
1. buy the HP Pavilion 300 keyboard
2. open the systemsettings UI and navigate to the keyboard shortcuts section
3. assign some action to one of the special keys that under the hood map to one or more modifiers plus the touchpad toggle key

OBSERVED RESULT

Incorrect mappings for Meta+Shift+Touchpad Toggle and Meta+Alt+Shift+Touchpad Toggle. 
Correct mappings for Meta+Touchpad Toggle and Meta+Ctrl+Touchpad Toggle.

It seems the combination of shift and the touchpad toggle key is the problematic combination.

EXPECTED RESULT

All keys can be mapped to an action of the users choich
