Hi,
For your HikaMarket question, please be sure to post in the HikaMarket section of the forum (we moved the topic).
The "show sold by" option is for the product listing ; your screenshot refer to the shipping methods.
Because you have the "shipping per vendor" option, the customer has to select one shipping method per vendor ; and HikaMarket will give names for the "vendor warehouse" depending the vendor name.
You can use a language override to change the text and not display the vendor name ; you can deactivate the "shipping per vendor" if that option does not feet to your requirement or you can use a view override for the "hikashop | checkout | shipping" to not display the name of the "warehouse" in the shipping selection.
