It was a typo, they explain it here:

Luckilly, the typo has actually provided some clarity of the timeline like that Take Back the Kingdom battle lasted more than a year since Snow got pregnant just after defeating Regina on the honeymoon. It also confrims that 1x03 was less than a year before 2x03 as Belle was Rumple's prisoner during the events of 1x03/3x21 but met Dreamy before he became Grumpy, who he ws in 1x10. :)
