"Folder Formats" doesn't work

I use single display mode.
And for example,there is 2 tabs "movie" and "download".At first they are sorted by modified time.I change "movie" to sorted by filename.And I open a subfolder in "download".It is sorted by filename automatically.Even if I save the folder formats for them.
I don't know why.

Are you aiming to change the default folder format, or to override it for specific folders and sub-folders of them?

override it for specific folders and sub-folders of them

How have you got things set up so far? Which steps did you do?

Can you see Path Formats for those two paths under Preferences / Folders / Folder Formats?

Yes,I can see that.
I am sure of that I save the folder formats correctly.
But I don't know why the folder formats doesn't work.

Is your Format Lock on or off?

Thank you very much!
It works right now!
