Why are vehicle expenses shown as zero?

[adwiz]

I entered all the info for my leased vehicle in the "Vehicle Expenses" section. On the summary page it shows allowable vehicle expenses as $3780.95 with business use part of 41.078%, but the CCA field is zero and in my self employment income summary vehicle expense is zero. I can't enter anything in the CCA field as it invalidates the record. I deleted the vehicle and re-entered the info and it comes out with exactly the same issue. What's the problem here?
