This file is a garment file (*.zpac) in which the fabric of the CLO is tied like a real ribbon and simulated.
The tied part is fixed with a pin.
Pin is not a problem at all when rendering, so you don't have to pay attention.
If the ribbon pattern is activated and continuously simulated, the tied shape can be released. It is recommended to freeze the ribbon pattern.
