Duplicated values AFTER OUTER JOIN

[murrego7]

Hi! 

I have a two tables:

First table contains info about actual sales per country and date.
Second table contains info about EXPECTED sales per country and date.

Some of the countries are not present in both tables, that is why I perfomed an outer join. BUT after performing this join, for the first table I get duplicated values as the dates are different for the both tables (not all the dates in 2nd table are present in 1st table and the opposite).
Issue

How can I fill the duplicated values with 0s like here:

I already tried this solution but I am not able to implement it.
