Leaking Sunroof

My 2016 Octavia sedan is leaking from the two front corners of the sunroof.

On extensive investigation, I have come to the conclusion that there is no front drain lines at all and that it relys solely on the rear 2 drainage holes and tube that i have easily located.

This does not match up with what i have seen and read online. There is definately no tube on either front sides down any of the A pillars as though it was not ever installed. 

Am I missing something here? Would this be standard to only drain from the rear 2?
