You wouldn't be flagged for spamming - a later submission overwrites an earlier one in the same category and erases any record of it. But it does put you back to square 1 if the editor chooses to review in date received order (a possibility).
But in this case there is no record I can see of an any submission in any case so you have to resubmit if you want to suggest it for review.
Having said that when I clicked on it to see if there was a more suitable sub-category (which you should do) I got a "The page you are looking for is currently unavailable" message. If I were reviewing and saw this on a submission in a category like that it would get no second chances - instant rejection. Some editors are as tough as me on that, others might give it a second shot. So if you resubmit, for goodness sake make sure it is stable.
