Switching post positions

When I post something.
My post switches it's position with another post.
It's getting annoying.
Can anyone fix this?

might be cuz someone else posts at that moment or something

I doubt that that.
Because I posted a post 1 Min before the next post.
And after the next post.
My post then switches positions with the next post.

I think it's a boards glitch. Happens to me sometimes, too. I think it helps if you refresh and see new posts in order to make sure you don't end up accidentally double post.
