[How to remove invisible npc when input and successrefitem function used together?]

If `successrefitem` is called after  `input` (or even `select`). When function is closed, there's a invisible thing left on the map with and 'ellipsis' (npc interaction thing) when you hover on it.
 

function	script	F_TestFuncHere	{
	input .@refine_count;
	successrefitem 1,.@refine_count;
	return; // also tried close or end. didn't matter
}

I use this function as item script.
