Importing traps onto lines issue

Kia ora!
When importing traps into lines that have the same number at the start (i.e. 55GR and 5GR) all the traps seem to get added to the line with the greater number (In this case 55GR). This happens even though the traps are assigned to the different lines in the csv file and has happened to me a few times now. Not a big deal at the moment and I know you’ve got a million other things to be looking into but just thought I’d see if anyone else has had the same issue?
