Double counting rrsp contributions

My RRSP tax receipt has two boxes.

One has my RRSP amount contributed in taxation year 2014

The other is called "Paid within 60 days after end of 2014".

For the first box does that include contributions made Jan 1 to March 1 2014? If so then I already included that amount in my 2013 tax return and I should be deducting this amount so I don't report it again in for my 2014 tax return. It comes down to the definition of "taxation year 2014". Is it Jan 1, 2014 to Dec 31, 2014 or March 1, 2014 to Dec 31, 2014?
