Measure Not Calculating Correctly

[joshs444444]

I am trying to figure out the cost inflation over time for a set of items.

I have an average unit cost measure, but when I pull it into a table I have, and line charts, it does not calculate correctly.

Right now I have the measure for average Unit Cost:

Average Unit Cost =

AVERAGEX( 'All Purchase Line','All Purchase Line'[Unit Cost])

here is what the table looks like:

I want the total to be the sum of all rows in the table, divided by the count. However this is now what it is doing.

I have a couple filters applied to the table:

One for year (2020-2023) another for Item (top 50 by purchase spend) and another by high spend (yes) -this is in the item table

My datamodel is here:

Please let me know if I can provide any further clarification

Any help is appreciated.
