[Risolto] The German translation changes

Background of the issue:
I am trying to ensure that the German translation of my website title reads 'IoT-Lösungen nach Maß.' instead of 'IoT-Lösungen nach Mass.' The online translation editor shows the correct translation as 'IoT-Lösungen nach Maß.', but the translated webpage displays 'Mass' instead of 'Maß.'

Symptoms:
The translated webpage uses 'Mass' instead of 'Maß' in the German translation.

Questions:
Why does the translated webpage display 'Mass' instead of 'Maß'?
How can I ensure the correct translation appears on the webpage?
