Hello,

1. Navigate to the Header Builder and for the social links set the same value as the Desktop header has: https://take.ms/G6FMY

2. Seems that it comes from the Appearance -> Customize -> WooCommerce -> Store notice: https://take.ms/8SIdx

So remove the text, clear the cache and recheck the issue.

3. Try to translate it via the Loco Translate, more detail is here: https://take.ms/GcOI7

Kind Regards
