For anyone else if they ever get this weirdness, I had entered 'none of these above apply' on Amend self-employment details (page 1) as none of the options applied. This options seems not allow you to pay NICs.
I choose "My 'basis period' (the self-employed period for which I am taxable) is not the same as my accounting period (Optional)" and then made my basis the full tax year and now it's showing an amount of NI to pay.
