Date Format in Power BI changed to a different language on Power BI Embedded Version

Morning everyone,

Please can you help me.  I am using a Microsoft List to feed into Power BI embedded version and for some reason the date has changed to a different language.  I assume this is because someone has messed with the column in the list, but I'm struggling to resolve it.

I've tried regional settings on the list but this hasn't resolved it.

Can anyone help please?

Thanks so much.
