I would say that there's an error in the "CameraFilterMetricprofile.xml" file. In my experience Fusion processes the files in alphanumeric order and as soon as it encounters an error it stops loading any further thread files. To test this you can move this file or perhaps rename it adding a "z" at the beginning of the file name so that it reads "zCameraFilterMetricprofile.xml". It won't of course fix the file but it should allow Fusion to load the remaining thread files.
Hope this helps.
If this answers your question please mark the thread as solved as it can help others find solutions in the future.

I've created a Windows application (and now Mac as well) for creating custom thread files for Fusion. You can find out about it here. Hope you find it useful.
If you need to know how to offset threads for 3D printing then I've created a guide here which you might find useful.
If you would like to send me a tip for any help I've provided or for any of my software applications you've found useful, you can do this via my Ko-Fi page here.
