Market capitalization (not a metaphor)

SOURCE TEXT: What is the difference between using social media for multicultural marketing and communications vs. general market marketing and communications?

SURPRISE!!! 

My Word capitalizes the word 'market' whenever I translate it into Spanish: market > Mercado (the Invisible Hand at work, ha!). I wonder if this happens in other languages (French, Italian, Hungarian?...)

Oh, and it also capitalizes words like "god" > Dios. 

Food for a socio-linguist thought I guess...
