On my homepage I have added the elementor widget that shows products from the categories. On the first tab it keeps with the woocommerce setting of having no decimal points. However on the other tabs the decimal points show when they shouldn’t. Please see the screenshots attached.
Please make the full backup of your site and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by WooСommerce.
