Hi Sylvain,
I'm not an expert on normalisation and the option of reducing the amount of
non-linear basis functions was already mentioned. Perhaps you could also
think about the option to increase the amount of regularisations, to heavy
or extremely heavy (via 'defaults').
See for example:

regards,
Simone.
