Hey all,
so i have build this Automation which copys comments to a certain parent Request Type whenever a comment is made: A Sales Order Ticket is always a parent of a Sales Order Service Ticket.

The Automation works just fine when i manually create a Sales Order Ticket and link a Sales Order Service Ticket to it via link issues (not Sub-task). All Comments made in the Sales Order Service Ticket get copied to the Sales order Ticket as an internal note. Done. 
However: This does not work in the following example which is way more important:
We have an ERP linked to our JIRA Cloud Instance. Sales Order Tickets and Sales Order Service Tickets are almost always created automatically whenever an order including Services is placed. This process is triggered from said ERP. They have a Parent - Child Relation.
Whenever a comment is written in a Sales Order Service Ticket, that has been created automatically the Jira Automation states to following Audit Log ( No actions performed):

I cant seem to find any obvious issues with our Parent Child relations in Tickets. At least I cant spot the difference between manually linked and automatically linked Tickets.
Does anybody know what might be the root cause for the problem we are facing?
Is this more of an internal API ERP topic?
