Doubts in vocab

In skill building vocab check section, can I not write the synonyms mentioned for the word in definition?
Eg. Aggrandize -
Definition says : enhance one’s power or standing.
Synonyms also include magnify

But the chatgpt feedback says that magnify lacks the essence of enhancement of someone’s power or status.

Similarly,
For the word : ambivalent
Definition says unsure as well but still the chatgpt feedback says wrong
Could you please help me out with this?
