To resolve this issue, you may need to adjust the variant order for each product in your Shopify store. To do this, you can follow these steps:
- Log in to your Shopify account and navigate to the “Products” section.
- Click on the product that you want to edit.
- Scroll down to the “Variants” section and click on “Edit options”.
- You should see a list of the available options for your product variants. Drag and drop the options to change the order in which they appear.
- Once you have made the changes, click “Save”.
By adjusting the order of the product variants, you should be able to ensure that the size options are displayed in the correct order on your website.
If this does not resolve the issue, you may need to seek assistance from Shopify customer support.
I hope this helps!
