Hi solid-honey,
Yes, please get in touch with Tech Support if you have a moment.

I have written a report, but if this is the only request, then I guess it will not show up in the future.
Here is my workaround for now.
Merge this file
2024_Matrix.c4d
and pick one of the three.
Sorry for the trouble, this is not fun! I agree!
Cheers
