11.21 seems to have a bug in default sorting: the folders don't sort alphabetically nor do the files within the folders. The attached screenshot shows the problem: folder "R\P\Pink Floyd" sorts before "R\0" and the filenames are out of order too.

Left-clicking on the "Relative Path" bar fixes the sorting but there seems no way to make that the default. The correct sorting cannot be saved in to a session file either. My laptop was still on version 11.18, and I tried a similar comparison, which sorted correctly. I auto-updated the laptop to 11.21 and the sorting problem happened when I ran the same comparison. I thought it might be related to me running three parallel threads during the comparison, but it happens identically with one thread. I also wondered if the problem was caused by doing a comparison with a network share; the problem exists between folders on the same computer.
I then installed 11.18 on my main machine (the one that provided the attached screenshot) and the same comparison sorted correctly. I don't have backup up installers of the 11.19 and 11.20 installs, so don't know where between 11.18 and 11.21 the error was introduced.
