[TYPO3-english] Can't add new content column

[Olga Zhuravleva]

Second column doesn't appear at backend page list.
I've written in Ts:

TCEFORM.tt_content {

       // Remove content colums in backend
       // 0 = main
       // 1 = left
       // 2 = right
       // 3 = bg images
       colPos {
               removeItems = 0,1
       }
}

TCEFORM.tt_content {

       // Remove content colums in backend
       // 0 = main
       // 1 = left
       // 2 = right
       // 3 = bg images
       colPos {
               addItems = 0,1
       }
}

   subparts.CONTENT < styles.content.get
   subparts.CONTENT_BOTTOM < styles.content.get
   subparts.CONTENT_BOTTOM.select.where = colPos = 1
