Filter a column present in only one table

Hi,

 

I have two tables with the columns "machine" and "month" with the format 1-12 for which I have created support tables for the many-to-many relationship.

First of all, even if it works for now, I would like to ask you if this is the correct way to filter the two tables.

 

I have to filter by month, machine and external at the same time. the problem is that External doesn't work, probably because it is only present in one table. How can I also filter for "EXTERNAL"?
