Card visual > data label formatting across languages

Hello, I have a card showing the number 5,600 as 6K. I have set this rounding under Format > Data Label > Display (thousands).

In Germany, a colleague looking at the same report sees 6Tsd. This is too wide and breaks the formatting of the report.

I would like to keep the whole report and its notation in English regardless of browser setting. Does anyone know how I can set the report / visual / data point to be consistent across browsers?

I have an embedded report served from PBI Service. Thanks.
