David, I could answer with certainty if you shared a screen capture or a recipe file if this occurred with a saved recipe. But I do have a guess. The three rotation settings (dealer, vulnerability, and hands) defined on the left of the page all operate independently. The Hands rotation setting causes only the Shaper and Cards to rotate. If you have dealer and vulnerability set to anything other than Rotate, then they are fixed for that recipe.
If your goal is to make scenarios for two students, I would set dealer and vulnerability to Rotate, then set Hands to rotate 90 degrees (one seat) after every 1 board, and specify 16 for the Number of Boards. Then, after generating the 16, I would select the boards I want for my students. Why 16? Because I consider vulnerability part of the scenario, and 16 boards with those settings will give you every combination of dealer and vulnerability on the duplicate scoresheet; you can then choose which of the 16 you want to use. It's not enough (for me) for two seats to just have the scenario's points and shape and to be dealer (unless, of course, the lesson is to demonstrate how to operate with different vulnerability).
So, if you generate 16 boards with the settings as I described, you could then use just boards #1 and #11 for your two students. #1 has North as dealer with None vulnerable; #11 has South as dealer with None vulnerable.
If this use of rotation and board selection seems laborious, you could always set up two recipes, each with the dealer, vulnerability, and key card location that you want. The rotation settings are a convenience for rapidly varying a recipe, but there's nothing wrong with having bespoke recipes by seat.
Finally (phew!), I no longer include https://bridgecommaoutahead.substack.com/p/route-64 in my user guide because parts of it are obsolete (max deals is now 2048, not 64), but it includes a good discussion of how I think about board number/dealer/vulnerability/hand rotation combinations.
If I select rotation 180Deg after 1 deal, the hands do vary between North and South but the dealer stays North. Any idea why?
