CMS Single column layout with no sidebar?
 

Thought I did everything. Made a grid, no sidebar, 1 column (100) named it "full page". Went to layout manager and made a "full page" layout with only 1 content column. Cleared CMS cache. Went to section and chose full page layout and content columns = 1 column, saved. I get 1 column that is about 50%???????
