/wiki doesnt give the correct information of pokemon even if we change it, example :
i've enable ExternalJSON and tried to edit the biome spawn of Chikorita, but /wiki still return the old value (even after a restart), also other thing like TIME doesnt work too.
But Numel work so its not all pokemon and i can't understand why actually

I have had the same issues as listed above. Using /pokereload to reload the external jsons as well as restarting the server does not fix the issue. I primarily tested with legendary Pokemon. I wanted to add the original spawns for a few Pokemon as well as add a few biome opportunities for some Legendary Pokemon to spawn. When modifying Rayquaza, Groudon, Kyorge, and Articuno (galarian: added in the latest update), the /wiki command did not reflect the changes. In fact, originally, Kyorge remained unedited but the /wiki command displayed all of the ocean biome variants. The same instance with the legendary Pokemon I was testing. I should mention, the edits and the spawns themselves work correctly in-game. Only the /wiki command is having issues displaying the correct information. However, I think it is relevant to mention how some Pokemon like heatran, though I did not want to edit them, I wanted to see if the changes reflected the wiki. To my surprise, all of the changes matched the /wiki as intended. As such, it seems only certain variety of Pokemon, not just legendaries, these were only used to test, have the issue to have a specific set of information displayed. It seems to default to show all biome varients but in some cases the time is incorrect as well. I made sure all of the json files were valid, no errors in console, and I did wipe the external jsons with the same resulting effects.

the issue is know now, and hope will be fix in next version
