I used a translation tool hoping it wouldn't affect our communication.

When moving multiple folders to a single folder or the root directory, the subfolders within these multiple folders may be unexpectedly moved out of their respective folders.

This problem recurs over and over again across multiple vaults. This problem still exists when using only one plugin in newly created vaults and folders.

On my computer, I created a new vault, downloaded this plugin as the only plugin, restarted Obsidian, created some folders and randomly grouped them until I had combined them down to 3 folders.
Then, I create a new folder inside Obsidian and select the three folders I just created, drag them to the newly created folder, move them to the new folder, but the number of folders increased to more than 4, and the folders inside those three folders leaked out. After repeated operation, the number of folders becomes more and more.

When you close the plugin, the problem goes away.

This problem is probabilistic, and it seems to be more likely to occur as more folders are selected, and as the operation of moving them to the folder or root is repeated more times.
