Sold about a week ago, I've got trades created around that far back that are still unsold to counter this.

It's untradable until February 10th, showing it was purchased on SCM.

Conclusion: The second sold isn't actually a sold, and the sellers at 8 and 8.33 show the first sold is outdated or an outlier.
