Just checking the difference, not so significant meaning...
Anyway, I guess it's due to the behavior when slot counts is missing (regarded as slots=1) and it's oversubscribed unintentionally. I'm going out now, so I can't verify it quickly. If I provide the correct slot counts, it wll work, I guess. How do you think?
