Fixed Asset Incomplete Additions Tile - Last Updated Field

We have a tax asset analyst who ONLY has access to the tax asset books. We have found that although she only has access to the tax asset book, her name is showing within the CORP book. She did not make any of these transactions, but is showing up as the "Last Updated" person. This is concerning for our Corporate fixed assets team. Can anyone tell me why this would be happening? Screenshot below of what I am referring to. On the dropdown menu for her "Assets" module, she cannot see the US-USD book, only her FED Tax book.
