when searching Colognes forum, SOTD threads appear

[i_shaved_something]

I notice in Search function something strange, i.e.
I enter "hammam bouquet", and select 'search all terms', and then choose search within 'Colognes and Aftershaves' forum only (leaving the other fields as default values). The results returned all say 'Colognes and Aftershaves' in the left hand side, and most are cologne related, but notice several SOTD threads are also listed there as well. Clicking these does take you to these SOTD threads, but they are somehow classified under Colognes and Aftershaves now instead of the SOTD category?
Not sure if something got corrupted in the database, thought I'd mention it in case it wasn't noticed or symptom of some other problem to be aware of...

Thanks
