I have these import rules:
ORD|id:2|oc:Your order has shipped via #3 with tracking number #4. |
ORD|id:2|us

And this csv file:
ORD,25,UPS Ground,123456789
ORD,28,UPS 2nd Day Air,987654321

When I import an order update csv, a comment is added but it appends "ORD" to the end so it looks like this:
"Your order has shipped via UPS Ground with tracking number 123456789 ORD. "

And only the first line item (order #25) is processed. What's wrong with the way I have my rules and/or csv set up?
