Minecraft : 1.20.1
Mod Loader: Forge 47.3.7
Tide : 1.3.3

When I add a profile by datapack like this:

The profile would duplicate in the journal:

Additionally, if I exit the world and re-enter it, they would start doubling themselves...

I can be sure that this is not caused by myself writing the file twice, because when I delete the json file, both of the duplicates disappered.

Using /reload will also cause these profiles to duplicate.

Okay, now I can make it clear:
This is not caused by entering a world, but because of using the /reload command. I have a KubeJS script that automatically uses /reload each time entering a world so I understood it wrongly.
However, I believe this is still a bug, and I hope it can be fixed!

Fixed as of 1.3.4!
