Weird Behavior.

Since I updated sources in NotebookLM tools, when I go back to NotebookLM, I am getting errors for the sources and I can't open them, however I can open them in NotebookLM tools... any ideas?  Screenshot for what it looks like in NLM.

I found the issue... they files belonged to a person who was no longer with company and were deleted. NLM reflected they werent there Notebook Tools didn's see that error, but downloaded a null file.

Here is the updated screenshot. When I look inside Notebook Tools, I can see the file... Cannot share the notebook unfortunately. So I downloaded the file from Notebook Tools and the files is empty... it seems they are zombie files...
