Is this a board glitch? Raelian thread?

just wondering if there is a board glitch or if anyone has had the same thing happen.
In the my ATS area, for some reason I have a double listing on the raelian thread...
I only posted once, but these redundant two instances seem to "hang" onto the top slot of my page, even if I just posted to another thread.

so...
double listing of a thread,
and seems to stay on the top regardless.
in the My ATS page...

board hack, glitch?
any ideas?

thanks SO or others...

It will happen ever so often....

I'm not entirely sure what triggers it - Somtimes it happens when a mod edits a post...

When you go to try and delete just one, it usually ends up deleting both....So I usually just ignore it and go on....*shrugs*

Thank ye kindly sai'

I understand it well now... thank ye
