Texture Misaligned

Hi there,

This is probably an issue down to me learning the process. But I would like to know what has caused this problem with our model texture.

Basically, for the most part our project is looking great, but inside the buiding we have scanned there are vertical wooden columns where textures from other areas have been incorrectly placed. I'm guessing this is something to do with the settings we have used. Please forgive me if this is really something very obvious - I am still getting my head round the concepts invloved.

I will attach 2 images, one that shows the incorrectly placed teture and another where you can see the texture and unwrap settings.
