CalculateDraftOrder mutation not return availableShippingRates in default language

[MagaliWD]

Using this mutation with only French language published on our Shop return availableShippingRates in French, that's good. But if English language is published and French language is set as default, this mutation return availableShippingRates in English.

Did anyone have the same problem or an idea of the origin of this bug?

Thanks
