Fractal scales 1-10 are the same daily chest. Since you completed both a 9 and a 10 in the same day, the 10 a mere 30 seconds before reset, there would be no second chest. Had you completed it 30 seconds after ideally you would have gotten a proper tier 1 chest. The chest tiers changed with the Fractured update. Though I must say there have been several times before and after Fractured update where the game simply didn’t give me a daily chest and it’s a frustrating bug.
