CCA Rental Property Depreciation half rule does not calculate on Turbo Tax

Hi, 

I am trying to claim the CCA building depreciation on my rental property for the first time. I know that the first year, the half year applies, but it did not get applied on my turbo tax, and doesn't let me input it manually. I input the cost of the building and class in Section C and then it calculates automatically, but does not include the first half year calculation. WHy is that?

Also on my T776 form, the CCA created a loss on my rental income, which it is not supposed to. Please advise why it is doing that, and I cant change the amount of CCA to claim. 

I had already blanked out the expenses and on purposedly changed my income amount to be lower than the CCA amount, but it still created a loss. Is there not a function to limit how much CCA it can claim? If there is no limit why can I not change the amount manually?
