Navbar dropdown arrow visible on some subforums

Link to the page

Note: this occurs in anothers sub forums too, this is not the only one

its because we used to only have "Openbullet"  when the forum was started so thats why its showing it but it is something we will fix later as its not doing any harm .

that applies to every forum you are talking about because over the year we have added more subforums .
