After splitting my pension income with my wife, why does the full amount from my T4A still appears on my tax summary?

I entered the amount from box 16 of my T4A as instructed. Later in the process, I split a portion of that amount on my wife's tax form as instructed. When I went to the tax summary section, the full amount of my pension income that I entered earlier still appears in my tax summary as income. The summary for my wife does show the transfer amount I entered. Should the total on my summary for pension income not be less the amount I transferred?
