Django modelformset_factory with prefix not scaling

[martin...@gmail.com]

Hello,

I have been trying to scale modelformset_factory and run into the issue that modelformset_factory is working correctly when I implement with just 2 formsets. Code here: https://gist.github.com/martin1007/6474f3a7f14540bae729e8b4d31f8ca2

But when I try to scale it using lists it does not work. Code here: https://gist.github.com/martin1007/71e07c27aeeb265fa9d55eea3f33aebe

Any ideas why is that? Thank you in advance.

Best regards,

Martin
