Hello so sorry for the issues you're facing regarding the changing of language in your store. Click on the store and check backend language setting.

You cannot edit platform system shipping error messages such as that like you can a themes wording using locale files or admin settings. You may be able to edit "Shipping method" to "Shipping method (3 jar minimum)" @JMLunabean wrote: the store has a 3 jar minimum (they sell jelly/jam). Generally you want to solve this BEFORE a customer even gets to the cart. For the online sales channel through messaging, and theme customizations that add 3 at a time or a pack builder UI, or via bundling. For multi-channel it can be saner to sell packs then use an automation app to do the inventory sync'ing. There may be shipping apps using the new checkout-shopify-functions feature that could do "something" but you'd have to dig and experiment. An alternative workaround is maybe making a very high priced shipping rate with it's title trying to message about the minimum to get better shipping rates. If you need this consulting on, or the automation or customization built then contact me by my email for services. Contact info in forum signature. ALWAYS please provide context, examples: store url, theme name, post url(s) , or any further detail in ALL correspondence. Save time & money ,Ask Questions The Smart Way Confused? Busy?
