They have been installed backwards. Pull rudder pins, switch the assembly around so that the casting/blade currently on starboard is moved to port (and vice versa), then reinstall rudder pins.
This is a common mistake when removing rudder assembly for trailering or whatever. It's sort of like setting sail with the plugs out.........some folks have done it; the rest will! It results in severe rudder toe out and will make your cat sail like a dog!
For future reference, (looking forward) the tiller arms should be slanted inboard relative to the blade (Google Ackerman Steering if curious as to why) and the hiking stick yoke should be slanted forward. Some folks put a little electrical tape on one side of the crossbar (or red tape on port, green on starboard) as a reminder.
