Hi,
First, please check that you do not have a view override for your product page.
Because you're using HikaShop starter you should not have the product custom fields ; but if you have install the "sample data", it is possible that it creates elements related to the product fields. These fields are related to specific products so if you create new one, you would not have the fields. By recreating your products it could fix the field attribution.
