Harbinger scarabs not working as intended

So ive been using harbinger scarabs for 1200+ maps and ive noticed pretty consistently that the scarab that makes it so they only drop one type of currency shards doesn't work properly ive got multiple screenshots on Playstation that show one harbinger under that modifier dropping 2 to 3 different currency shards i feel like ive been losing money all leauge no wonder probably gonna either try to wait for a hopeful quick fix otherwise im just done for the league because i cant get my currency farmed properly like seriously no wonder it took 1200+ maps to see only 3 frac orbs which is kind of pathetic
