Weird Incompatibility with Visible Traders

[MrBeast1107]

There seems to be weird conflict/interaction between villagerconfig and Visible trades mod. When using both at the same time, duplicate trades are generated when a villager levels up. I dont have any other mod modifying trades.

MC Version : 1.21.11
Mods Version : Latest
VisibleTrades + VillagerConfig Datapack = Duplicate trades
Only VisibleTrades = Works as intended
Only VillagerConfig Datapack = Works as intended

VisibleTrades + VillagerConfig Datapack before trading:

VisibleTrades + VillagerConfig Datapack after villager levels up once:

VisibleTraddes without datapack after villager levels up:

Tier 3,4,5 level ups also generate duplicates.
My Datapack : VillagerChanges.zip

Temporary fix : With datapack enabled, I trade with the villager once to fix their trades, then disable the datapack and level them up. I think this works [I could be wrong] because visible trades mod generates all tier trades at once and stores them.
