Change League of a Club

Hello,

i wanted to edit the teams and leagues of the Chinese, Japanese and Korean leagues since all 3 leagues have finished the season. So for example i wanted to put Gimcheon Sangmu into the K-League 1 since they got promoted and Suwon into the K-League 2 since they got relegated. But if i save the database and want to load it, it still shows Suwon in the first division and Gimcheon in the second division. However i tried it with PSG and put them from Ligue 1 to LIgue 2 and there its working perfectly fine. Just not for the 3 nations. Is there a reason for it and if yes how can i fix it?
