unable to download to Calibre

I've had 3 Kindle book that I can't load to Calibre. They just show one folder and several files that can't be opened. They have file extensions of ASC,PHI,XJF and XJR. The usual blue file with the book that normally allows the load is not showing.

I did get a new Sue Grafton book normally but the 3 didn't; 2 Allison Brennan books included.
These books do open in the KIndle? Anyone experiencing this or have a solution?
