The man page says that -j takes one value.  You have two values following
the -j.

       -j FIELD
              equivalent to `-1 FIELD -2 FIELD'

It appears that you want either this:

$ join -t: -a1 -1 1 -2 1 pnn pnum >pacetrep

or

$ join -t: -a1 -j 1 pnn pnum >pacetrep

When something does not work, you should carefully read the man
pages.

$ man join

Most times it is also useful to also try using --help, which also gives
the information needed to solve your problem.

$ join --help
