Build result reason showing post chain actions instead of stage name

Problem

In Bamboo 8.0.1, the build results Summary and History tabs are showing the string "post chain actions" instead of the stage name when on a manual run

Environment

Bamboo 8.0.1

Steps to Reproduce

Set a stage as manual, run the Plan and the stage. Follow the results page

Expected Results

The build results page reports the stage name on the Plan's Summary and History tabs

Actual Results

The build results page reports the "post chain actions" string instead of the actual stage name on the Plan's Summary and History tabs

Workaround

None

Notes

A regression from 8.0.1+

The "Stage name" shows correctly during the build. But reverses to "post chain actions" once completed.
