Included pairs file throw no method isless()

Hello, I'm using CircuitScape 5.13.3 with Julia 1.11.0. I'm running a task with pairwise mode with the attached ini. CS_data.zip The error seems to deal with the included pairs file. I tried keeping only the 3 first pairs listed and it work but not with the full 1346 lines txt file (attached). Is there something wrong with the format of this text file?

Thanks a lot for your help. Laurent
