I wrote, "Jane Doe has not let the expectations of work. . ." Instead, I was told to write, "Jane Doe does not let the expectations of work. . ."
Was what I wrote in error? Every time I wrote "has" I am told to replace it with "does" without any context as to why.
Another example: ". . . with that came more responsibilities" I was told to replace "came more" with "comes". Where was the error in saying "came more"? The subject's past position had changed, which is why I spoke in the past tense.
Is my grammar that bad? Everything I wrote was crossed off without context as to why I should delete what I wrote.
Background: I am a British English learner who lives in the US if that helps. This level of correction is making me feel like I have a long way to go.
