Another Relationship Issue

I am trying to compare estimates to actuals for projects.  Here are the relationships:



Job Master has Unique Job#s and are linked to the estimate table as well as the cost detail table.

Although, when I try and compare estimates to actual costs, I keep getting a repetition error:



Depending on which table I pull the 'CostItem' from changes which column has the repetition.

I can't wrap my head around how to correct this as I am not using a calculated column, or a measure for the data fields, just 'Amount' from the JobCostDetail table, and 'EstimatedDollars' from the JobEstimatesOriginal table.

Any thoughts here?

Thanks in advance,
