The visible sort order of files and folders is not updated.
I'm using the default sort order "by type". For some folders, I put the sort order "by date". I found that if you go to another folder, the last modified version is displayed, but in fact everything is correct with the sorting of folders. If you close and reopen Thunar, then the option is again displayed, as I have "by type" even in the folder where the sorting by date is. It is impossible to correctly determine in the Thunar' menu which sort order is in a particular folder. In version 4.16 everything worked correctly.
