selection based on another field in a table

[sekrish]

So I have a table chart in qlik sense that needs to show

Task_Number -Subtask_Number-Subtask_Owner_Name

most of the basck end data tables are associated with the task_number. the subtask_table has only the subtask_owner_uuid and there is a seperate emp table that has uuid and names which i am loading as below (without any left or inner joins)

[emp_names]:
LOAD
uuid,
uuidname
FROM [lib://.......qvd]
(qvd) where exists([subtask_owner_uuid],[uuid]);

issue i am facing is 
when i put in the table dimension in the chart to show the subtask-owner-name it is cycling through ALL the uuidnames in the uuid table for every subtask instead of just the subtask_owner_uuid from the subtask table

e.g:
Task_Number1-Subtask_Number1-EmpA

Task_Number1-Subtask_Number1-EmpB
Task_Number1-Subtask_Number1-EmpC

Task_Number1-Subtask_Number1-EmpD

assuming we have only 4 employees. i am guessing i need to use a set expression to fix this, but i cant seem to get the right one.  can anyone assist. i am guessing this is  a fairly common issue

changing the uuid field name to be exactly the same in both table and taking out the exists clause seemed to fix it, but its loading a lot of redundant uuid's  now. in the load script..
