Please find my comments in bold. Still now Issue is not solved.
1. Create a new Workflow model This is fine
2. Add an OR Split. Select branch1 as default route. Save This is also fine
3. Open the OR split properties, I still see the default route as branch1. Change it to branch 2. Save and Close This is also fine.
4. Open the workflow model again. See the properties and it is showing as branch2 as the default route. This is also fine. Upto thi steps fine. But the issue happens after this.
After completed this all steps, I start workflow for one of websites from siteadmin. Then I went to AEM Workflow Inbox and right click on workflow and try to complete the workflow task. Here I am seeing in drop down by default as branch1 . But I should see by default branch2 in my drop down as shown in below screenshot.
