How to recover missing profiles and distros

Hi! I am not sure what happened, but all of a sudden all distos and profiles are not listed any more. I can't see them neither in CLI nor using web interface. However, all actual json files are there in /var/lib/cobbler/config/profiles.d/ and /var/lib/cobbler/distros.d directories. Does anybody know of an easy way to restore those except manually entering them from json files? All systems and repos are just fine. I tried to do 'cobbler sync', but it complained about the system referencing missing profile. This is cobbler 2.0.11 on Scientific Linux 6.0 Thanks, Leon
