Tested with QDS 4.4 Built on Jan 10 2024 21:32:26

How to reproduce:
1. Create a project and open Model Editor
2. Add a new model. There should be now models "book" and "Model"
3. Try to select between the models. It should change the table content.
4. Now delete the model named "Model"
5. The table view does not change to the content that "book" model has
6. If you create a new model again, now you can change between the models and the table content will also change.

Also if you delete all the models, the table will show the content of the last deleted model.
