First: Try to follow the section 'REPORTING BUGS' in 'man parallel'.
It will make it easier for us to help you, and it may just uncover the
problem.

Second: For the first situation: The only time I have experienced
something like that was when the space in the shell script was not a
real space, but some Unicode space lookalike character.

For the second situation it seems there is a bug in GNU Parallel. It
should of course treat {} and empty as the same. That would have been
easier to spot, if you had simply made a tiny example showing that
issue:

$ echo ls /bin/ls | parallel {}
/bin/bash: ls /bin/ls: No such file or directory

$ echo ls /bin/ls | parallel
/bin/ls

Conclusion: Try removing {}. If that does not help, replace all spaces
with real spaces, and newlines with newlines. If that does not help,
follow  the section 'REPORTING BUGS' in 'man parallel'.
