The following will explain what dependencies cause the dependency icon to appear on the Release Tracking page under iterations.
.Can you help us figure out what the issue is with the Release Tracking view with how it’s displaying and showing dependencies?
In order for a dependency to appear under iterations on the Release Tracking page the dependency must be be listed as a successor. Only successors will appear. Predecessors will not be included.
To verify this you can open the feature and click on the dependency and go to the dependency icon in the upper right corner.
This will bring up a list of the dependencies that are attached to the feature.
Only the successors will be included.
