@twilitegxa - hrmmm well that doesnt make any sense and I've not heard of this one happening before. Although I did see it the other day with another Plugin... I deactivated it and reactivated it and things we back to normal. Totally weird but true story.
Can you please post this on our blog under the recent 3.8.13 blog post where somebody from the WPEC team is more likely to be in a position to help.
