PFAC rule resolution is giving job org unit but workflow is not resolving it

hi

MDG Customer Workflow issue.

there is std workflow template - WS54300003

there is dialog task - TS75707980

std rule is the agent assignment here - 75700139

configuration for above rule is - MDGIMG - general settings - process modelling - workflow  - other workflow - Assign processor to change request step

if USER is assigned in above config the workflow is taking it

but if JOB is assigned then workflow is not taking it

we have assigned JOB to Role and Role to Userid.

when i simulate the rule in PFCG, it is giving result as the correct job object

it should work right ?

please advice, if something is wrong in config.

thank you in advance
