Key Del is dysfunctional in left pane.
It doesn't matter whether or not Preferences - Behaviour - "Move deleted files to trash bin instead of erasing from disk." is checked.
Enforcing a deletion independent of that setting by hitting Shift+Del doesn't work either.
The usual confirmation dialogues corresponding to settings "Confirm before deleting files" and "Confirm before moving files into trash can" do come up as usual.

The context menu in left pane does not get adjusted to the setting "Move deleted files to trash bin instead of erasing from disk.".
It never features "Delete" as it should when the setting is unchecked but always "Move to trash" and does perform this action, too.

None of these problems exists in right pane where everything works as expected.
