C++ Function remove not 1 Item from 200 it removes all 200

This is for the skillbooks, but when i stack the skillbooks and i click on a 200er stack, not one book disappear, all books disappear, i'm trying to fix this since 4 hours, the only result i had is, that i think NOTHING sucks more than c++

 

here the RemoveItem1 Funktion (i copied the RemoveFunction cause i want only to use it for the skillbooks)

void ITEM_MANAGER::RemoveItem1(LPITEM item, const char * c_pszReason)
{
	LPCHARACTER o;

	if ((o = item->GetOwner()))
	{
		char szHint[64];
		snprintf(szHint, sizeof(szHint), "%s %u ", item->GetName(), item->GetCount());
		LogManager::instance().ItemLog(o, item, c_pszReason ? c_pszReason : "REMOVE", szHint);

		// SAFEBOX_TIME_LIMIT_ITEM_BUG_FIX
		if (item->GetWindow() == MALL || item->GetWindow() == SAFEBOX)
		{
			// 20050613.ipkn.½Ã°£Á¦ ¾ÆÀÌÅÛÀÌ »óÁ¡¿¡ ÀÖÀ» °æ¿ì ½Ã°£¸¸·á½Ã ¼­¹ö°¡ ´Ù¿îµÈ´Ù.
			CSafebox* pSafebox = item->GetWindow() == MALL ? o->GetMall() : o->GetSafebox();
			if (pSafebox)
			{
				pSafebox->Remove(item->GetCell());
			}
		}
		// END_OF_SAFEBOX_TIME_LIMIT_ITEM_BUG_FIX
		else
		{
			o->SyncQuickslot(QUICKSLOT_TYPE_ITEM, item->GetCell(), 255);
			item->RemoveFromCharacter();
		}
	}

	M2_DESTROY_ITEM(item);
}

I hope I could get help here, I'm really fucked up with this -.-

ITEM_MANAGER::instance().RemoveItem1(item);

Did you try in this form:

item->SetCount(item->GetCount()-1)
