[Opening] Is Witeuim always like this?

I had double surgery at Gangnam ㅇㅁㄹ for the second time because the first buried one was released. However, I spent close to 200 for the top tulle + investment material, but I knew that the top tulle was open in the front direction and was meant to be opened in the upward direction. But even when I compare the before and after, I don't know what to say. It feels like it was just fixed on top, but it doesn't seem to have any nicks or cracks. It was originally like this. Is there any place that does this? The horizontal length doesn't change and it feels like it's just fixed upwards. Is this how it's supposed to be? I actually thought I was cutting in front ㅠㅠ
