What is the penalty for staying less than a minimum stay?

I have booked the following flights on KLM:

Buenos Aires - Amsterdam    
fri 4 nov 16              

Amsterdam - Barcelona
wed 9 nov 16    

Barcelona - Paris
wed 16 nov 16   

Paris - Buenos Aires
sun 20 nov 16

I have already paid for it and a friend told me to read about the conditions of the tickets, (which I had before without paying much attention); Tickets say they have a minimum stay requirement of 7 days. Why did they let me book this way then? Shouldn't this schedule be unavailable if it's not allowed?.

What's the penalty for this? Am I gonna pay more for some of the tickets when I'm about to check in?. Are they gonna allow me to board?

EDIT: All 4 flights say this:

Minimum Stay: A minimum stay of 7 days is applied.

PS: None of the Destinations are "main", I built the schedule because I wanted to visit all 3 locations and the price was good.

If KLM Ticketed your itinerary, meaning they processed the payment and issued tickets for the flights, you're fine. They check all these rules beforehand and would not even let you book an invalid fare.
