Custom Layout Sections in 2.10.2

I've used Ben's guide (http://www.contao.org/forum/topic/161.html) to create custom layout sections on other sites.
However, this is the first site I'm building with 2.10.2. Although I follow all the steps in order to build the custom sections, they will not show up in the "display in" drop-down when I create a new article. Any thoughts? Thank you!

I'm glad I'm not the only one who uses the old forum - Leo wanted to close it down at one stage :shock:

Works for me on Contao 2.10.3.

Name them in Settings (comma seperated). Save.
Page Layout::Custom sections::Custom layout sections. Select them and Save.
Now they're in the Frontend modules::Included modules::Column dropdown
Now go to Articles:: new article:: display in (and there they are)

Try upgrade to 2.10.3 perhaps.
