I have my UI language set to English (US). My country/region is Paraguay (South America). One of Paraguay official languages is Spanish.

The problem is that Plasma assumes (wrongly) that since my region is Paraguay, I *must* have a Spanish UI, which is not the case.

For example, today is Thursday. When I put my mouse over the digital clock it says "jueves" (in Spanish). This is even despite the fact that I have selected English (US) as my UI language.

Reproducible: Always

Steps to Reproduce:
1. Select Paraguay as your country/region in System Settings
2. Select English (US) as your system UI language.
3. Put the mouse cursor over the digital clock. The tooltip will shown any date info in Spanish.

Actual Results:  
Date info shown is in Spanish

Expected Results:  
Info should respect UI choice. In this case the info should have been in English instead.
