On various screens (eg Administration|Roles|Edit Role, Edit Contact Purpose), the Available and Selected lists are multi-select. However, if you do select multiple items and attempt to move them to the other list, then only the first is moved.

Suggested fix: turn off multi-select on the lists so that the user can only select one item and thus cannot get confused when they select multiple items and only one is moved.

Note that this is a minor minor problem - I only found it when I cocked up the authorities set for a role in the conversion data input and I was trying to manually correct the problem in the converted database.
