RAW DNG seqence: Image Sequence option greyed out

As you can see, I am... in fact, selecting only the first image in the sequence. It's not the file name. I also tried a batch rename of "clip_XXXXX.dng." I also tried using slimRAW to create lossless "Premiere CC compatible" DNG sequence (the one you're looking at). No... I don't want to import into AE first (makes you use camera raw to color correct the clip, and create a lossy clip for editing). I don't want to use a lossy clip (MPG) or the like for editing. I need to edit the RAW. Why? Does it really matter? I just do. Please help. I just want to import an image sequence, and PP 2017 won't let me do it!
