The library names seems suspiciously like you downloaded the official version 5 library (or parts of it) and tried to add it to kicad 4. There is a backport of said library intended to be used in kicad 4. More details see: Kicad 4.0.x backport release of kicad v5 library is now available on github.
You can also manually run the check compatibility script. Details see: How can i install a specific version of the footprint library? (Second entry)
