What does this mean?

I saw my first ultrasound ‘after visit notes’ today and this is what it says

Baby was measuring exactly 14 weeks on the ultrasound. I already got the NIPT at 11 weeks and this was the result

I think my NIPT results are good so why are they recommending me to get another test? I didn’t see my doctor at the ultrasound, just the ultrasound tech. Any thoughts on what this could mean? TIA!
