However, HikaShop manual shipping plugin value always saved even I have choose the Delyva shipping method and make the payment. But when show in Additional information shipping field is always HikaShop manual shipping value on backend.

Hi,

We'll need more information to better understand the situation.
Could you provide a screenshot of your shipping methods listing in the menu System>Shipping methods ?
Could you also provide the necessary information to reproduce the issue on your frontend ?
