This change of file extension will occur automatically upon import to calibre if you have the DeDRM plugin installed and enabled. (This happens even if the file does not contain DRM.)
Quoth mentioned that they could be renamed but I've not tried that yet. I definitely have DeDRM installed, I've used calibre for many years, but kf8 is how it downloaded for me and it is how it still is in calibre. And as I showed you Calibre can't convert it.
This all sounds odd to me. I shall try later at just renaming the files and see if that helps.
