Do you have multiple corridor feature lines? Try setting the lacing on the node to Longest.
It is my corridor baseline and dyn ，can you tell me why？
Expand the preview of the data going into the corridor feature line input. The node heading into it indicates this is going to be a list of corridor features lines. As such you have lists going into each input, and lacing will default to shortest.
To resolve this. Swap to auto or use @L1 for the feature line input.
