Loot - Skin shards dissolves all shards?

Hey, I was told I should post this to the boards by support, but i am not sure which one to post to. When disenchanting a skin shard that has a stack of 2 and the champion is not owned it will disenchant all shards despite showing the total cost for just 1 shard for the confirmation of the disenchantment. I am not sure if this is by design or not but it is very misleading to have the value of 1 shard if it is going to do both. I would recommend giving players an option of how many skin shards they want to disenchant to prevent people from disenchanting all shards unintentionally.
