Neither choosing "Save & Close" nor selecting a different key will actually save the selection you made, my workaround was to swap to a different effect on the same key and then going back to "Select Skill Button". That worked for me.
Confirmed.
The event handler for the control was unlinked (a symptom of having ported this code over from SuperLemmix). All controls have now been double-checked and updated as necessary.
I've also refactored the list handling a bit so that only the currently-being-edited item updates (rather than the entire list!), making the UI a bit snappier.
Fixed in NLCEPlayer commit ebc4405.
