In the Web Office, any coupon with the Shipping Discount coupons display as "Free Shipping" in the Rewards Available box (in the Cart Summary panel), no matter the discount amount. This default text can be confusing if the coupon only gives 50% off shipping rather than the whole amount.
You can change this default Text Value, or others like it, using the Localization page.
For more information, see Web Office Localization.
Steps specific for the default "Free Shipping" coupon text:
Search for "Free Shipping".
Or, search by the String Key name
The Edit String pop-up window opens.
Edit the Text Value as necessary.
Click each language box and enter the translations.
