Game limiting Shattering Runes to 20

When transferring shattering runes to my crafting inventory - this is resetting the number of shards i have on the UI to 20 (it may say i have 22, when transferring extra shards, it then changes to 20)

Update: seems to be decreasing sometimes when used, sometimes it doesn’t, but the number will have decreased later on when i check it.
