Hash missmatch in parity

[fr34kyn01535]

Using Geth/v1.8.0 i've created a private network with the genesis configuration from:
https://gist.github.com/fr34kyn01535/ec902fe6bdece6ae0c32a4232c8c138d
When transforming it using parity-spec (result also in the gist), it seems to cause a missmatch in Parity/v1.8.7.
