When I enter the data of the prizes to be won, the information is not updated.

Hi thanks for helping me,
When I update the prizes, with the name of the prize, the personalized coupons and change the color of the cells, when I give it to save it does not update the information and the information is re-established by default in the plugin …
It does not save the information that I enter and personalize when I click save.
