I wish it were otherwise, but the solution is that we have to try to fix how Quik Link interprets the item code with the leading space. IC formats its item codes differently when all characters are not used, depending if the item has one segment or multiple segments. You are not doing anything wrong, and I couldn't find a workaround in the meantime.

I'm glad that you've been happy with Quik Link thus far, and we'll try to address this as soon as we can.
