Harvesting a fruit from HC's tree gets "fruit blocks"

[RisingInIris2017]

Versions

Mod version:

Pam's+HarvestCraft+1.12.2zg

Forge version:

Singleplayer.

Installed mods:

Among these mods, I have known that Hunger Overhaul and Cuisine Mod have their own right-clicking harvesting function.
But I have set
enableRightClickHarvesting=false
in Hunger Overhaul's config file, and set
B:BetterHarvest=false
in Cuisine Mod's config file.

Game does not crash.

Description of the problem

How to reproduce:

1. Right click a grown fruit block on a HarvestCraft Mod's fruit tree.
2. Both the edible fruit item and the fruit block itself drop.
3. Set enableEasyHarvest=false in HC's config file.
4. Break a grown fruit block, it drops both itself and fruit item.

This problem can lead to fruit block duplication, which means players will not need to grow trees and be able to turn any oak tree into an HC fruit tree. It's over-powered and game-breaking, that's why I post this issue here.
Hope to get your help which is highly appreciated.
Thanks in advance.
