Hi,
you should just remove the shema.org data from the product page, in this section:
<span itemprop="price" content="29">$29.00</span>
so it becames:
<span>$29.00</span>
you can check it after the removing to see if Google still sees the offer price here: https://search.google.com/structured-data/testing-tool/
Kind regards, Leo
