Feedback search returns feedback over 12 months old

A search on my feedback shows neutral feedback that was left over 12 months ago. When will this disappear?

The transactions may be more than 12 months old, but the feedback could have been left up to a couple of months later. The feedback will age off once it is more than 12 months since the feedback was left.
