Measure from PBI dataset blank under "Aggregate"

Hello everyone. 


I am very new to the Report Building tool, but I cannot find a solution to this very simple scenario (or maybe I am not understanding the other entries in the forum).

I want to replicate this simple matrix:


Where, as can be seen, the third column is the result of the second divided by the first.

In Report Builder, I get something like this when I build the query:


Great! The numbers are the same. Good. Now let's add it to a matrix:


Note that I select "Aggregate" because I don't want the averages to be summed. This I learnt from Paginated Reports in a day tutorials, it can be seen in at 16:08.

After finishing the matrix, I get an empty result:


For some reason I cannot undestand, if I enter the query editor and leave it, the query seems to update itself (why does this happen??) and now I get the following:


Again, I am completely new to the topic, and I'm sure I must be missing something very basic. Could someone please point me in the right direction?

Thank you in advance for your time,
