Opening 10x chests yielded 9x pouches and 1x 100 shard instead of 10x pouches

I opened a chest that was supposed to guarantee a Life Shard Pouch x1 (L). I picked the “open 10” option. However, I received 9x that, and 100 Destruction Stone (bound). Additionally, the chest opening window is stuck on the loading animation until I close it.
