changed the variable idx value from i to the last index of resultGroupsList

UOP1_Project/Assets/Scripts/StateMachine/ScriptableObjects/StateTransitionSO.cs

 			List<int> resultGroupsList = new List<int>();
 			for (int i = 0; i < count; i++)
 			{
-				int idx = i;
+				int idx = resultGroupsList.Count - 1;
 				while (i < count - 1 && conditionUsages[i].Operator == Operator.And)
 				{
 					i++;
