Nitwit villager became a farmer villager after world conversion

There is a world conversion bug with the nitwit villager (green profession). When I convert the world from Legacy Console Edition to Bedrock Edition, the nitwit villager becomes a farmer villager.

Steps to reproduce:

1. Go to Legacy Console Edition, click the play game button, and then click the create world button to start a new world from the play menu. Change the game mode to creative mode.

2. Obtain the villager spawn egg from the creative inventory.

3. Spawn a nitwit villager (green profession).

4. Exit and save the world and exit the Legacy Console Edition.

5. Go to Bedrock Edition and click the settings button. After almost reaching the bottom, click the "storage” button. Then, click the “storage” button and scroll down until you see the old worlds option. Finally, click if you want to convert your old Legacy Console Edition world to Bedrock Edition.

6. Finally, click the converted world from the settings menu.

7. Check to see if the nitwit villager has became a farmer villager.

Observed result:

Nitwit villager becomes a farmer villager.

Expected result:

Nitwit villagers are supposed to stay the same after the world conversion.
