Well, that’s debatable since the notes are enharmonically the same, scale tone III. So it’s a spelling error, it names the correct note, and the correct chord type albeit with the wrong spelling.
Of course, to respell, it’s as simple as clicking on the Enharmonic shift parameter in the Info Line
I also teach. I would not encourage a student to use any kind of automated chord analysis, personally, I would insist that they use their own ears. And if they refuse, I ask if they actually appreciate those ears, or, if I might cut them off to give them to my poor students who are earless.
I mean, what would Kodály have said?
