8 Tridents disappeared from ghast farms separate trident killers | Experimental Mode enabled

I have silentwhisperers ghast farm (https://youtu.be/8Tii5zjK2K8) and today I noticed all 8 tridents are missing. They were in 8 trident killers of the same type. This was the first time visiting the farm since enabling experimental mode, it worked fine for weeks before enabling it. They were 8 unenchanted tridents in 8 separate trident killers. I never get in pick-up-range of the tridents and I don’t have them in my inventory
