When creating via the API (and not setting a type) the default is used, 
which works with aarch64. Only if 4m is explicitly set, it errors.
The ui user can't set the version, that's why I changed it there.

To me, the second option seems better, should it work.
I don't like the idea of letting the user provide a parameter and 
silently ignoring it.
