Can someone please tell me, whenever i tried to run the DX API V1, the case I'd is created with 'C' like c-1 or c-2 like that, but when I tried to run the same case type manualy the case instance is creating like I - 100, I-101, like that, both cases are same and checked the prefix I'd in definition created as "l -" but the instance is creating in different manner in API Response and normal instance .
