Autoscheduling reverses the scheduling of dependent tasks

[Anand Tekkam]

I have 2 tasks T1, T2. Both have story points and is part of a scrum board. T1 blocks T2.

While auto scheduling the tasks using Plans, T2 gets scheduled before T1 whilst it should be the other way.

What should I be checking to see if our Jira is configured correctly or is this the expected behaviour (which is very unlikely as documentation also suggests T2 should be scheduled after T1)
