Incomplete data while saving layer to JSON

Dear All,

I am having an issue with the attack-navigator, exporting (saving) layer functionality. I create myself a new layer from scratch -> Enterprise ATTACK

I will enable the Show IDs in Layer controls (this probably has no significance to the problem).

And then I download a layer in JSON:

If I count the techniques displayed in the browser (navigator) I get - 235 techniques.

In the downloaded JSON file, I can only see 119 techniques. For example, I am not finding: T1046 Network Service Discovery.

I am attaching the download JSON file: layer1.json

I would expect that the techniques in the downloaded JSON match with the techniques visible on the screen. I would like to use the JSON to annotate the techniques, and then upload to attack navigator.

If I export the data to Excel, I see a complete list of techniques - including T1046

Thanks a lot,
Lukas

No source file, test, or entry point is named. Reproduce the issue by creating an Enterprise ATT&CK layer, exporting JSON and Excel, and comparing their technique lists; done means the JSON contains the same visible techniques as the Excel export and can be uploaded again.
