Duplicate Post Appearing on MyATS Your Subscribed Threads

Under MyATS the following Post is listed twice in the Subscribed threads area. Just wondering if this is normal or not, because I don't recall seeing this before. I know in a query somtimes you'll pickup the same thread multiple times due to multiple criteria, but I would think the only criteria was my username it should only show up once. Please excuse my ignorance in this matter and if you don't want to explain how this works a link would be appreciated. TIA
