I'm using an advanced branch to create a new Story for each label added to an Epic but am unable to then also create the Sub-tasks to go with each Story.
It seems I'm unable to add a Branch rule / related issues component inside of the Smart Value Branch. If I could move the last branch under the "Then: Create a new Story" this automation would work perfectly.

I get this error in my audit log
Can't branch rule as it requires issues to have been previously created by this rule. More than likely you have not yet created an issue or the issue(s) were created in an another 'If' block or branch - these would then not be visible outside of that block/branch.
