How to remove my duplicate post?

[NewDay1]

Hi - for some reason my recent post showed up 2x on investory ally.  It won't allow me to remove.  Is there a way I can remove one of them?  Thanks.

When I encounter this, I visit the thread and find the "report to moderator" link in the bottom right corner of the first message, and indicate it's a "duplicate thread".
