Thanks for reporting the problem.  But I believe the problem is in
your use of the command.

  sort --check kk2.sort
  sort: kk2.sort:2: disorder: ice_cream%1:13:00:: 07510835 1 1

Files for join must be sorted.

Sort the files first and then all lines will be joined.  Here is an
example of sorting on the fly using some bash specific extensions.

  join <(sort kk1.sort) <(sort kk2.sort)
  ice_cream%1:13:00:: 07510835 1 1
  life_style%1:07:00:: 04875322 1 2
  part-time%3:00:00:: 01131371 1 21
