There should be a bevel ob both sides of the blade but they do not need to be exactly the same width nor is there a need for the same width for the entire length of the blade on any one side. The only requirement is that there is some bevel on both sides.
It does not sound like your razor is warped. It sounds like your honing stroke is in need of more practice. Work on the one side with the 1200 until the bevel is established then do a pyramid or two.
Just my $.02,
