Thank you, Jonathan for your active involvement.
Your issue was a bit different, related to bypassing the home job and the external won't be bypassed. It's addressed by a known defect:
EXTERNAL JOB WITH SCOPE IS NOT BYPASSED
PROBLEM DESCRIPTION:
The external job with SCOPE parameter remains in EXTNL status and will not be
bypassed if remote application is created after the real job is bypassed.
The fix correctly bypasses the external job with SCOPE parameter when the
remote application is created after the real job is bypassed.
The fix is still in QA. If any one is interested, please open a support ticket for it.
