Shop Page title

No matter what I try I cannot either remove or edit the page title on my shop page. It sits below the header and above the content. It shows as Archives: Products. In other themes I can usually edit the word Archives to something else but in Jewelry Theme it just refuses to be edited or deleted. I have tried to edit it within Yoast but that doesn’t work. I have spent hours searching for the solution. I can’t be the only person who doesn’t want my shop page to have a header called Archives? It looks clumsy and the word suggests that the content is old. I just want to either delete that section of the page or change the word Archives to something else but the theme doesn’t seem to allow it, which is a shame because I like the theme, but cannot live with this, so please could someone help point me in the right direction. Yoast>Search Appearance>Taxonomies doesn’t solve this.
