ACT_RU_EXECUTION create multiple rows after the flow starts

I had a workflow with activiti: 5.18.0 which when started, creates a single row in ACT_RU_EXECUTION. 

I decided to create a new flow and migrate existing instances to the new flow. For which I tried with activiti version 6x, 5.22.0 and even 5.18.0. New flow creates multiple row (2 rows) in ACT_RU_EXECUTION table for every new instance.

 

Now if I work on migrated flow it throws an exception:

(Note: when tried with 6x, i also used v5 compatibility jars).

The exception comes because old execution have only single row per instance. while all the new flow have 2 rows (could be more):

old flow data: 

ID_  | REV_ |  PROC_INST_ID_ | BUSINESS_KEY_  | PARENT_ID_ |  PROC_DEF_ID_ | SUPER_EXEC_ | ACT_ID_ | IS_ACTIVE_ |  IS_CONCURRENT_  | IS_SCOPE_  | IS_EVENT_SCOPE_ | SUSPENSION_STATE_  | CACHED_ENT_STATE_  | TENANT_ID_  | NAME_  | LOCK_TIME_
38575005 | 3  | 38575005 |  NULL | NULL | selfSignup:4:38575004 | NULL | registration | 1  | 0  | 1 | 0 | 1 |  2 |  | NULL | NULL

 

new flow data: (first row has parent id)

29 | 1 | 5 | NULL | | selfSignup:1:4 | NULL | categoryInputTask | 1 | 0 | 1 | 0 | 1 | 6 |  | NULL | NULL
5  | 1  | 5 | f81b6787db8d4769 | NULL |  selfSignup:1:4 | NULL | NULL | 0 | 0 | 1 | 0 | 1 | 0 |  | NULL | NULL

Note: I do not have any subprocess in the new flow. All I introduced new is the timers but before it reaches timer, it fails.

 

(following line execution fails for old flows:

propagatingExecution = (InterpretableExecution) execution.getParent();

from AtomicOperationTransitionDestroyScope class )
