When KEYBOARD clause is used we can click with the mouse on the Num, Caps and Ins items to toggle their status. But, specifically for Num and Caps, the status change is not reflected by the keyboard light and this brings to an inconsistency between the status itself and what the keyboard lights say.
Possible fixes are:
1) remove the item click at least on Num and Caps (but I would remove it on Ins also).
2) use the appropriate API to correctly change the lights status.
For the point 2, the following sample is from Francesco Saverio Giudice:
