It was causing a lot of issues so I had disabled it, but it's still enabled in some places. I have to look at re-enabling, I think I fixed most of those issues
This is right, it will only allow what's marked as OK in $fillable. But you always have to have $fillable set, if it's not there, it won't get filled (got bit by that a couple of times). For example with Frontend/PirepController::store(), I use $request->all()
We'll need to see the code for the store() method and also what the model looks like.
