US Client with T4

I have a US client who moved there and bought a home two years ago. In 2025, he has a CDN T4, issued for stock options that have vested.

I've entered his new address, called him a non-resident but still a CDN citizen.

In the final review of the tax return, I am getting FIX messages for the following...

- Address is incomplete with no province listed (but he's in the USA).

- CPP contributions have been entered incorrectly. But I out them in Box 16, where they always go.

Can anybody help with this ? Is it something I did or didnt do at the start ?
