Assembly shape does not match with Loft shape

Hi everybody, does anyone have experience with the assembly shape not match with loft shape when using the civil connection to form a loft? The straight link can’t link up the curve link even I already assign the code, why?

Look at the log file and recreate the subassembly, there is nothing else to do. You might want to double check the AppliedSubassemblyLinks for more complex geometries

I find it will happen when the arc link connect to line link, may be i need to break down the arc and line to do it. Thanks for your reply Paolo.
