When I modify Job data in Job Data component, I am getting rows inserted into Ben Program Par Audit

When I modify Job data (example change of employee class or pay group ) in Job Data component, I am getting rows inserted into AUDIT_BENPROPAR ( Audit record of BEN_PROG_PARTIC) even I do not make any changes in Benefit Program Partic ( see 2nd snapshot below)

I used below Audit Trigger to track changes in Benefit Program Partic record

I would like to track only the Benefit Program Partic changes to be loaded in AUDIT_BENPROPAR when we changes the data through Job data component, not the Job record related Data changes.

Could you please suggest.
