Incorrect rewards for ranked PVP match

What you were expecting to happen, and what actually happened?
I defeated a player named Quantum in ranked PVP. I expected to get a new set of three opponents to choose from. Instead, I got the same three opponents, and my battle log did not reflect the fact that I had just won a match.

I defeated Quantum again (hey, three trophies, four event stones, and 3000 gold), and did not get rewards commensurate with a 3-trophy match. Screenshot attached below.

What are the steps to make it happen again?
Heck if I know.

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
