[support] unpublished blog post published anyway?

hi all, i have a blog post that under 'published' the box is definitely not checked, but the post shows up as published anyway. this was a very sensitive post and i had to delete it entirely so that people wouldn't read it. the fact that it was published when i thought it wasn't has created some problems! what am i doing wrong here, why did the post show up as published? thanks for help! will
