They named it Cup with a capitol C, to distinguish it from the regular cup. It's still confusing though.
I've pointed it out like last season in the minor suggestion thread, but i didn't receive a reply whatsoever.
At least in my history, all cups have a capital C (unless it's 'tournament' with a small t, but even this is consistent for both B3 and the national cups, if you check Tooroo's history). It's simply the exactly same message for both.
