When you save your Xtext editor, it triggers a reload of the resource by Sirius (they do not share the same editing domain or resourceSet).
During the load, your resource creates a new model in memory. The elements previously known by Sirius cannot be retrieved: you modified an attribute which impact the URI fragment. The Sirius graphical elements reference the old elements.
If you launch a refresh (from the tool bar of the diagram), it might retrieve some content but the layout will be lost as the (re)loaded model is a new set of objects.
You mid find some hints in the following resources:
- White Paper on Sirius and Xtext
- Talk Integrating Xtext and Sirius: Strategies and Pitfalls: video, slides
- Blog post presenting several ways to from the Sirius editors or the properties
