"Don't wish" showing up when not selected

I don't think I ever noticed this before. When looking to swap with someone this morning, I seem to have many of my items showing up with both the “Wish” and “Don't Wish” symbols, but on my page, only the “Wish” is selected. And there are many of these. Am I doing something wrong or missing something? Photo below is an example. I have it as “I wish” but the colour codes shows that I don't have it, I don't wish it and I do wish it.

You probably have a ‘Don't wish’ criterion or setting that sets them automatically.
You should look up My wishes and check your settings and criteria.

Hmm, I see what you mean. I just noticed that I have the following:

1. Coins, banknotes or exonumia

Please specify what you are looking for. The categories you don't select are considered as not wished.

And I recently only selected banknotes. So, you are saying that by default, all coins became “not wished”. 

Thanks, that clears it up. I'll fix it right away!
