Thanks for the info flaps, it's helpful and informative and I do appreciate it. It might've been waiving that did this - my understanding initially was that everything is waived unless you say otherwise as that would be intuitive. That the only preferences or constraints are the ones you enter. So I didn't have anything waived. It was simply "Give me a line with 6 days off," and if you can't do that "Give me a line with 5 days off," then 4 days, then 3. Barring that, "Give me reserve with 6 days off," "give me reserve with 5 days off," etc. I thought that would work since it didn't have many parameters and allowed the next option down if not the first.
