Missing Heirloom Shards

I had 150 heirloom shards the last time I had played a year ago in 2025, I came back to playing the game and went to redeem one of the universal heirlooms and noticed they were no longer there. I don't remember ever spending them as the only heirloom I have is from merging my console account with my PC account many years ago. If it is possible to look into this to see if it is a bug it would be greatly appreciated!
