I just disenchant 2M 479k and I received 2M 100K wtf?

Hi there guys. This morning I pressed “mass disenchant button” it wasn’t working properly. After several clicks it finally worked, but then I realised I had 2M 150k instead about 2M 600K arcane dust (I had about 177,000 arcane dust before disenchanting + 2M 479k when disenchant). I feel scammed I want my archane dust back.

Here is the proof

There is a known visual issue for the mass disenchanting numbers being incorrect:

thanks for the reply
