Hi,

We have checked your site and did not find our theme influence on Woocommerce Germanized plugin functionality. We have compared our theme product page layout with WordPress default theme Twenty Nineteen and default Woocommerce theme Storefront and didn’t find any difference. Please check the screenshots and videos:

Woodmart default product: https://prnt.sc/p0kq0j
Twenty Nineteen default product: https://prnt.sc/p0kq91
Storefront default product: https://prnt.sc/p0kpqy

Woodmart variable product: https://prnt.sc/p0kyii https://gyazo.com/f09e96648277a111ea2e2ea3563dfdc9
Twenty Nineteen variable product: https://prnt.sc/p0kysn https://gyazo.com/6cec4e0e25a054e384ca8169e3f7b441
Storefront variable product: https://prnt.sc/p0kyoj https://gyazo.com/60a8191cd7963f9e5c1ca3d6517e1428

Your product page prices look the same on other themes, that means issue that you described did not caused by our theme and, unfortunately, we cant change plugin functionality via WordPress theme. Please try to check Woocommerce documentation or contact with Woocommerce Germanized support.
