Equipment Tracker miles not adding up.

I have 2 shoes listed in my Equipment Tracker:

1) Asics Gel-Kayano XI (BLK) Current usage (44 miles)
2) Asics Gel-Kayano XI (WHT) Current usage (6 miles)

For some reason the mileage on the second pair is off. It says I have 6 miles on the shoes but I have well over that. I wonder if the SQL query that derives the mileage is doing a "LIKE" comparison and picking up the first pair of "Asics Gel-Kayano XI" and not getting to the "(BLK)" and/or "(WHT)" which an "=" would do.

Just a thought.
