Hi Siebe, Just to agree with Edmund and Mauro: selecting "energy" and changing data type from "raw" to "XAS" should help. But, you would have to do this for every file, which is not ideal.
The file reader is trying to guess whether data is in energy (and if so, what units are used) and whether it is really XAS data or some other kind of data. I suspect that it is defaulting to "raw" because the energy column is not labeled "energy", but "col1" -- it sort of looks like the reader is not doing a good job of guessing what the columns mean. Posting a file would help diagnose why it is guessing wrong. The file reading does try to guess what beamline a data file came from, so if you send a file, maybe we can add enough hints for files from that beamline to work more reliably.
