It's not just parallax shifted but looks like the wrong inclination. I haven't compared the elements but it's obvious the orbital elements are very wrong. Inclination is out by 60 or so degrees.
The path shows DA 14 traveling between a point south of the SMC to a point south of the LMC.
The horizons path has it traveling mostly northwards accelerating during the night with a small and pretty constant eastwards motion.

I have just checked my copy of Starry Night Enthusiast and it is Version 6.4.3 as well. Since I last looked, Simulation Curriculum have released an automatic update that includes Asteroid 2012 DA14. Their orbital path almost matches the data that I manually added to the new asteroid objects but it is still a long way off when compared to the JPL data. Obviously, I will be using the JPL data for my location that I plotted onto the paper star charts.
To be fair, I am surprised that they added Asteroid 2012 DA14 to their updates. This is what they have to say about NEO's on their online help site:
Starry Night's asteroid data file (the Asteroids.txt file in your Sky Data folder# contains a selection of interesting objects. There are far more such objects available than we include in Starry Night; if we included the hundreds of thousands of known asteroids, the average home computer would not be able to run the simulation. In addition, the orbital data for some near-Earth asteroids #NEOs) are changing so quickly that we do not include them, in the interests of accuracy.
The rest of SN's help information for NEO's can be found at this link:
