Date Table relationship not working!

Hey guys!

So, I have this relationship between my Invoice table and my Date Table:

But this is not working. When I try to see the invoice amount in a simple matrix with my date table this is what happens:

These are the two fields I'm trying to relate:

Thank you in advance!
