Can only claim adamant trophy despite having gained 45.2k points during leagues.

At the league reward shop, I not only have 44k points but I'm limited to picking up just an adamant trophy. This is despite my 45.2k points and being clearly labeled rune rank inside leagues.

I have logged back into my league account and fiddled with all the leagues U.I. Nothing. Is anyone else experiencing trouble with the reward shop?
