Data source has values, yet it's showing no values when I input this into Power BI

[Anonymous]

I'm using a Teradata database to connect into my Power BI dashboard. 

When I've ran this data through Alteryx and looked within the database itself, all of my data is there. 

However when connecting this into Power BI,  one of my column's is entirely blank where there should be values there. 

Has anyone encountered this issue before or does anyone know how this can be fixed?
