Virtual element field displays but is duplicated for every work item

[Y_D_ABAPER]

Greetings all, first let me apologize as I am extremely new to ABAP, hence forgive my confusion. I am currently experimenting with an abap class that determines the current approver for work items. I am using virtual elements to determine this field which is displayed in my cds view as follows:

@ObjectModel.readOnly: true
@ObjectModel.virtualElement: true
@ObjectModel.virtualElementCalculatedBy: 'ABAP:Z_TEST_CLASS'
cast('' as abap.sstring( 12 )) as CurrentApprover,

My virtual element displays a current approver in my fiori elements preview, however, the same user is shown for every work item and I am completely stumped as to where I am going wrong. From my understanding the code should work correctly as I have:
 - Used the correct virtual element interfaces and methods
- Specified an internal table of type of my CDS view
- moved it_original-data into my local table
- have specified the fields that are required in my get_calculation_info method

@AbhishekSharma Do you have any possible insights on the virtual elements implementation?

just debug it. not just looking at the code.

Maybe the user shown is the user which is used for the workflow. Sometimes this is an special user which is used for the work items to proceed.
