A box job is completing after the first job completes and not waiting until the other inner jobs run.
Check if the job definition has the box_success field set with any values (valid or not).
If it does, that impacts the job's run or flow.
Review the job definition and the desired flow.
NOTE - The box_success field should not appear in the output from autorep -q -J <jobname> if it is not set.
To unset the field use JIL and supply the option but with no value.
Example:
update_job: examplejobbox_success: exit
