Double Files

Question

I have been using earlier versions of this great program for years.  I downloaded the latest version recently since I had to purchase a new laptop.  Program works flawless BUT in opening my subs from last night, I discovered I have double the # of OSC, bias and darks as I had created.  They are grouped with paired time/date stamps.  The first of each pair is extremely understretched whereas the second of the pair is over stretched and with a distinctive green hue.  Never saw this with the original and classic 3.0 edition.  What did I do wrong!

Remember that the RAW Files - .CR2 extension - are going to look Underexposed.  This is because they are the Accurate depiction of the Image Data that you actually collected through the Scope and Camera.

The JPG File is a "Processed" Image meant for Human Consumption.  It is Processed within the Camera, with a couple of Non-Linear Stretches and Saturation and Color Balance applied (most DSLRs apply a Daytime Process because that is the most likely Image Target and are relatively Heavy-Handed about it because that is what Consumers gravitate toward).  Along with the issues of the Lossy Compression applied as part of the JPG format, these are reasons that you REALLY want to stick to the RAW Data for your AP Imaging.  Your AP Image Processing software - DeepSkyStacker, PixInsight, StarTools, APP, Nebulosity, etc - will do it's Calibration with the Original Linear RAW Data, and then offer you the Tools to perform the Non-Linear Stretch and Saturation and Noise Reduction at the proper later time.

Can I only have BKYD Eos only create the RAW files and not the JPEG.  In prior program versions, I have never run into this program on my Xsi DSLR.  Is this dual capture mode option being triggered by the camera itself or the software.  I only want to deal with the CR2 files
