Exif ApertureValue is the wrong type?

I do some post-processing on jpegs created by CaptureOne LE from Nikon NEF files. This processing simply extract exif data from the file for generating a web page. Unfortunately, the program complains about every jpeg created by CaptureOne. I have finally found what I believe to be the root of the problem. Jpegs created by CaptureOne appear to include an exif value for ApertureValue that is of type SRATIONAL when the spec clearly calls for a RATIONAL. Some software can cope with this difference, but others cannot. Since it isn't really confirming to the specification, and since I can't imagine any possible reason why you would want the ability to express a negative aperture value, I hope that the developers can look in to fixing this. The NEF file does not have a value for ApertureValue, so it must be C1 that is calculating it and including it in the jpeg.

If this has already been fixed in a recent release, forgive me!
