- Data Mode can be changed by pressing on the circle located in the top right of the Entities Hierarchy window
- Before entering the Play Mode, the Data Mode is set to Automatic (Authoring), but after entering the Play Mode it switches to Automatic (Mixed)
- If Data Mode is set to Mixed manually, all data is visible in the Entities Hierarchy (unless it is changed after entering the Play Mode)
