British Columbia renter's tax credit says value is zero

Hi there, I'm trying to claim the new BC renter's tax credit. Under "British Columbia Tax Credits" I check the checkbox "NEW! BC renter's tax credit". Then I hit continue and fill out my renting info like address, rent paid etc., hit continue but then in the "British Columbia tax and credits summary" it says "British Columbia renter's tax credit: 0.00". Why is that and how do I fix it? 

And second question while I'm here, there seems to be conflicting information on whether rent paid refers to monthly or yearly rent. Which one is it? Thank you!
