Now we can see that we entered in the `enter_inner` para_inherents pallet method using the correct header

we call the `create_inherent_inner` method from `para_inherents` pallet with success

After the `BlockBuilder_inherent_extrinsics` we call the `BlockBuilder_apply_extrinsic` and here I think the problem exists.
The parent hash changes from `0x77d2ca4bd6c9fb35113aabe5b28f3da4cfc07b38233cabddda7f724f90e8e1d5` which is the correct hash
from block 1 to `0xfb0cf820badbcf6451effc8b6222c7564133d834f65a60e1d664a4d73fc248d4` which is a weird value taken from the
output of the line 45, and then it fails as it doesn't hold the validation at line

And if you compare the data value from the line 35 with the data value from line 45 you found few different bytes but this diff was not introduced by gossamer, does it?
