Performing an Inner Join in Power BI

Question

I'm currently having an issue displaying data in Power BI, this data is being retrieved from a star schema. Let's say I want to display data from 2 dimensions in one table of power BI, as you will see here, It looked like the power BI would be doing a wrong inner join.

The First two columns (Prac_Number and ProjectTitle) come from a table A and the column "Name" from a table B, these two tables are connected trough another table C (which would be the fact table).

to prove that what the power BI is doing, is wrong, I tried the following query with SQL Server:

SELECT DISTINCT ph.ID as [PRAC_Number], ph.ProjectTitle, phs.Name

FROM pracHeader ph JOIN pracDetails pd ON ph.ID = pd.HeaderID 
                    JOIN pracHeaderStatus phs ON phs.ID = ph.StatusID

ORDER BY ph.ID

and it worked out pretty well as you can check see here:

In other words, I just want to achieve this ^ in power BI. So if I have to create a custom column or something like that, where should I create it?, in which table?... Because the data is not matching correctly. Thanks in advance!

Reviewing the PowerBI output and your expected results, it looks like you might be missing (or something might not be correct with) the relationship configuration inside the PowerBI data model. PowerBI appears to just be listing the contents of each dimension table because it doesn't know how to relate the two. It could be helpful to see how you have your PowerBI relationships defined.
