Platform: iOS 13.5.1
Language: German
In the Setting app under Under "Datenschutz > Health > COVID-19-Kontaktprotokoll > Kontaktüberprüfungen > [DATE]" there is a string saying "Anzahl der bereitgestellten Schlüssel" followed by a number.
When increasing the text size in the Settings app, this string is leaving too little space to display the following number.

This should leave enough room for the following numbers to be displayed properly.
Issues of the iOS Settings app can only be fixed by Apple.
Ok. Chances were that those strings for app specific settings are provided by the app and could be changed by the developer.
