The Shipping Rates Calculator+ widget appears twice
Depending on the configuration, the Shipping Rates Calculator+ widget may appear several times inside a page.
This is indeed a feature, because some Shopify themes are able to display several cart forms at the same time. For example, a drawer cart and a pop-up cart can be displayed at the same time in a product page.
However, sometimes the app widget may appear several times incorrectly:
The most common reason is that the app is configured to appear on a particular location and also the app is placing the widget automatically on a different location.
The fix is really easy, simply disable the dynamic cart in the app preferences page on the Advanced preferences section:
Alternatively, you can remove the manual location for the widget and enable only the dynamic cart support.
We will be happy to configure the app location for you, just drop us an email if you need any assistance.
