If there is I would appreciate it if someone could explain it to me.
Well, a trim of -5.5 doesn't hurt anything. If you want the post-calibration trim to be closer to zero, then turn the gain down on the back of the sub and run the calibration again. A negative trim simply means the sub's gain was a bit too high.
However, what you may be saying is that the sub volume sounds too low after the calibration, which is a common complaint. If you follow my advice above, the lower sub gain and the higher Audyssey trim results in exactly the same sub volume after the calibration, which may be lower than what you like. There is nothing wrong with adjusting the sub's trim in the AVR after calibrating in order to get a higher sub level. Just don't touch the gain on the back of the sub after the calibration has finished.
