Nested Condition in Job Sequence

[isdslwg]

In my case, the following job sequence (Job Seq S) is setup:
Nested Condition A --> Job Seq A or Routine A --> Sequencer --> Nested Condition B --> Job Seq B or Routine B

For this master job seq S, the part "Add checkpoints so sequence is restartable on failure" is clicked. For Job Seq A an Job Seq B, execution action is set as "Reset if required, then run" and unclick the part "Do not checkpoint run".

When Job Seq S abort in Job Seq B and restart, however, it will be restarted from the very beginning (i.e. "Nested Condition A" instead of "Nested Condition B" or Job Seq B). I would like to know if there is any further setting is necessary such that Job Seq S will be restarted at the correct point.

Many thanks fo your advice.
