Visual Arts Supplement Deadline?

<p>Hi,
I am planning to submit a visual arts (drawing/painting) portfolio along with my application to Columbia.
On the Columbia Website, it says that the art supplement deadline for regular decision is January 1st 2014 and only ED applicants should submit the supplement until November 1st 2013. (<a href="http://undergrad.admissions.columbia.edu/apply/first-year/supplementary-materials%5B/url%5D"&gt;http://undergrad.admissions.columbia.edu/apply/first-year/supplementary-materials&lt;/a&gt;)
However, if I check the Slideroom website that is only accessible through my commonapp account it says that the deadline is November 1st for all applicants.
I am planning to apply regular decision, so I am a little confused about this. Can anybody help? When should I submit the portfolio?</p>
