Brightness & Contrast Adjustment Question

I am using 1.38A imageJ and I noticed something strange with the Brightness & Contrast adjustment (Image menu -> Adjust -> Brightness/Contrast) when viewing DICOM images.

When you open the B&C window on a DICOM (CT, MRI, or X-ray) the sliders for Brightness, Contrast, Minimum,and Maximum are already adjusted.  Then, if you click the Reset button in this B&C window it returns the sliders to a totally different position (likely centered).  

Why/How is imageJ starting B&C with the image already adjusted in the B&C window?  Does ImageJ automatically do a B&C adjustment when a DICOM image initially loads?

Thanks in advance,
