Why does confluence page is divided into two columns

[Silica Web Team]

Hi All,

If you can see and figure it out, the page is divided into two. it's not the complete page is in two columns. The actual format of the page is only one column. 

Other thing is as soon as I open page to edit, it display the page as one. This is happening randomly.

When you edit a page and it has two columns in edit mode, the Page Layout is probably set to two columns.

If you edit a page with two or more columns but they are just after eachother in edit-mode you probably have  several {column} - macros around the text

The author of the page has used a layout to make two columns.  You should be able to see that in edit mode.

Thanks, I am a page author and I have selected it as one column setting.

Ok, but the screenshot is of an edit of another page or another area on the page.  You'll need to be looking at the actual sections you are seeing as two columns.
