Describe the bug
Villagers who have their trades leveled up to Apprentice or higher have duplicate trades after having their occupations changed in any way. For example, a villager who has starting trades of 15 Coal for 1 Emerald and 1 Emerald for Iron Helmet that gets leveled up and then additionally gets 1 Emerald for Iron Chestplate and 1 Emerald for 1 Iron Leggings gets their occupation changed will have the two Apprentice trades (1 Emerald for Iron Chestplate and 1 Emerald for 1 Iron Leggings) appear twice.

To Reproduce
Steps to reproduce the behavior:

1. Level up a villager's trades to Apprentice
2. Change their occupation by destroying their workstation and placing another one or through Interact -> Locations -> Workplace
3. Check their trades and notice that duplicate trades exist and first level trades are gone.

Screenshots

1. A novice villager
2. An apprentice villager
3. An apprentice villager who had their occupation changed
