Locations Child Data Group returning records at unexpected events

We've a changes only extract to retrieve person, assignment data.

In assignment DFF, we've utilized 1 for Site-location(Attribute1) which LOV is retrieved as internal_location_code from hr_all_locations.

Extract Name: Worker_INT_XX

1. Root Data Group - PER_EXT_SEC_PERSON_NOW_FUTURE_UE

2. Child of #1 - PER_EXT_SEC_ASSIGNMENT_RANGE_UE

3. Child of #2 - PER_EXT_SEC_LOCATION_UE - yields location address details

Connections between #2 and #3 is PER_EXT_SEC_ASSIGNMENT_RANGE_UE.attribute1 = PER_EXT_SEC_LOCATION_UE.internal_location_code

So, here, even when there is no change in assignment or person block - Location address details are populating unnecessarily on random days on the very 1st run of the day.
