[Game Records] Ranked Solo / Duo displays promotional series incorrectly

Steps:

1. Enter into the promotional series in Ranked Solo/Duo from Bronze I to Silver V.
2. Win the first promotional series Ranked game.
3. Observe the Ranked records.

The Records show that I have a loss previous to the win. However, after checking several times my game records, I did not lose a game since I entered the Promotional Series. I won a game to get in, then won the first game, but the records show I have a loss previous to the win.

Please help resolve, since my (and possibly others') promo series may depend on this.
