Sephardim recite the Four Questions in the following order: 

1. "On all other nights, we do not dip even once. Why on this night do we dip twice?"

2. "On all other nights we eat bread or matzah. Why on this night do we eat only matzah? 

3. "On all other nights, we eat all kinds of herbs. Why on this night do we eat only maror? 

4. "On all other nights, we eat either sitting or reclining. Why on this night do we eat only reclining?

I could not find a source explaining the reason for the difference.
