I mean, even if
I want to request to add a year, I cannot. Like the comment beneath the year-list says: "most requests to add new year entries are sent for the wrong coin type." The referees most likely know what they are doing, and if you contact them, they can either add the year themselves, or mark the year list as un-varified, which means you can then request a new year (or, of course, they can direct you to the correct page, if yours is actually of a different type).
Now, onto the coin in question. From the pictures, I think it looks like the nickel plated steel version, and those types are not magnetic, so your type should actually be of this type:

And you can find an explanation here (since this has apparently been brought up before):
