Can confirm that this is still an issue. Hoping Samsung will notice and fix it at some point. Surely the Samsung developers have also noticed when using it themselves??
I'm new to Samsung Wallet, and this problem still exists by the looks of things. First impressions are is looks poor if they can't even get this working. You're at check out and look for the card logo and need to find it fast, not hold up the line! Funnily enough, their 'featured' partner "Tesco" works just fine.
