It seems to me that: the title they used is accurate, and if you want them to clarify it in order to diminish the reader's perception of the amount of power someone in that position has over policy, the issue is not with the article, but with your underestimation of how much influence and power Federal Reserve Presidents have.
It's fair to point out because people not in finance colloquially think of "bank president" as leader, not as "not leader, and not even actual president of the whole bank."
As for the influence of a Federal Reserve Bank of Minneapolis president, it's complicated. They're appointed by the board of directors of the Minneapolis Fed, and the directors are elected by the member banks — it's not a top-down process. To give perspective on size, the Minneapolis Fed has around $40 billion in assets, compared to the Fed's total of $8 trillion.
There's way more that also matters, but the Minneapolis Fed's president is nowhere near Jerome Powell in influence.
