Bug Report: Relaxed matching not working?

OK, this is a weird one but bear with me. My wishlist (https://deckbox.org/sets/47426) has several promos on it (FNM, Judge, GP, etc) that only exist in a foil printing. There's no non-foil version of an FNM promo Cultivate, for example.

Now observe this trade:

https://deckbox.org/trades/582693?s=4934

This user has a promo I want. But when I look at this user's profile, those promos do not appear as cards on my wishlist that are on their tradelist. They've marked it in their list as a foil promo, but in my wishlist I haven't indicated the foil-ness, so it isn't matched.

OK, let's say I change my wishlist to explicitly list it as a foil. That will cause it to appear in the trading opportunities section. But now observe _this_ trade:

https://deckbox.org/trades/582531?s=4934

When I look at this user's profile, they have indicated they have a promo that I want, but they haven't set that promo to be foil. So if I set my wishlist to be foil, the card won't appear here either! No matter how I enter the cards on my wishlist, I'm missing out on potential trades with people who have the cards, but haven't set the exact same details I have.

Relaxed matching is supposed to alleviate this, but as near as I can tell, it isn't actually doing anything. I see the same results from everyone regardless of what I set.
