Reproduction steps:
1. Open the attached “ASDQWE” project
2. Open the “Assets/Scenes/GameScene/LevelOne.unity” Scene
3. In the Entities Hierarchy Window select “Grid-0-0” Entity
4. In the Inspector Window Observe the “TileComponent” element

Expected result: The Entity has a reference to the element
Actual result: The Enity does not have a reference to the element

Reproducible with: 1.0.11 (2022.3.6f1)
Could not test with: 1.0.0 (2022.3.6f1 (package has dependant packages preventing from downgrading))

Reproducible on: Intel macOS 13.5

Notes:

* Removing the “ICleanupComponentData” inheritance from TileComponent.cs Script yields the expected results
* The issue is visible on any “Grid-” Entity
