The
{% with messages = get_flashed_messages(with_categories=true) %}
statement seems to be getting the flashed messages as a generator, and as such, can only ever be looped through once. As such, the `flash_messages` macro defined in `qc_app/templates/flash_messages.html` does not work as expected.
Instead, it will show the errors where it is first called on a template, and any subsequent calls will not show anything.
