Huh? I'm a native English speaker and the sentence looks OK.

Advances have demonstrated... The NLLB part is an adjectival(sic) phrase that modifies the noun "Advances".

Hopefully I'm not wrong...

It was a needlessly snarky way to word it, but they are right. The issue is the verb 'scale/s' rather than 'advance/s'
