OK, here's what I've found:
Those .raw files are unusual in that they contain some data that's not MS1 or MSMS. That's only a problem if you want to centroid the data, we have alerted Waters to the problem.
That's OK, though - you weren't using centroiding anyway. The issue with your Skyline document is that you're trying to extract DIA data where there is none. Skyline takes this DIA setting as a hint that the .raw file is msE data, so the function that's actually the negative scans is treated as the high energy msE data channel.
So, in your Full Scan settings, just set MS/MS filtering's Acquisition mode to None (you had it as DIA), and in the Filter tab set the Small Molecules Ion Types to "f,p" so that precursors are active, then reimport.
Thanks for using the Skyline support board!
