Bug - Normal Catalog shine!

[rexturtle1120]

Whilst perusing the catalog, I came across some fighters that had a sort of glint/shine on them, but I hadn’t unlocked them yet.
It seems at least to my knowledge, this only occurs with diamond fighters. Once I tap on a fighter with a “shine” to read its details, it still has a shine when I click off of it. However, when I scroll away and wait, say, 2 seconds. When I come back the shine is gone. This has happened to other fighters, all diamond at the moment. Not really a big deal, but I thought you’d like to know.
