It looks like the test operator "-f" is not functioning as described,
according to the documentation this should only return true on a REGULAR
file, not a symbolic link.

You can repeat the behavior by creating any symbolic link to a file or
directory and then using the test operator on the command line.

cd /tmp
touch test.txt
ln -s test.txt lnk2test
[[ -f lnk2test ]] && echo hi
[[ -L lnk2test ]] && echo hi
[[ ! -L lnk2test ]] && echo hi

The first test above -f should fail yet doesn't, the last negated symbolic
link test may be a workaround for finding a regular file unless you see
something wrong with that.
