I navigate to any directory in the file tree, enter the context menu and set it as the recording directory. Then I go to the recording screen, cancel out immediately and return to the file tree.

There is now a new directory, in the same place as the directory I just set for recording. The new directory has exactly the same name except the final 3 letters have been removed, and it is this directory that has become the recording directory. The original directory is still there too, but now it does nothing.

The workaround is to create a bogus directory with 3 extra letters, then delete it once the bug creates the new directory with the truncated name.
