There is a bug in the API dice parser that causes it to fail like this because of space use in the formula. I was hoping they'd fix this bug soon, but it's been hanging on for a while. I've not heard of this being an issues with the pathfinder sheet, but you might check that you don't have leading spaces in any of the stats used for initiative.
