The Adjustment amount is accurate, but the table is deceiving.
An adjustment when you have no visable percentage difference can occur when your current percentage and target percentage differ by less than .05 percentage points. Anything less than .05 percentage points is rounded down to nothing in your current percentage, even though it can represent money (depending on how large your assets are).
For example, say you have $100,000 in Global Bonds, and that represents 10.040 percent of your portfolio, and your target is 10 percent Global Bonds. Your difference would be .04 percentage points, which would round to 0. However, .04 percent of your entire portfolio (around $1,000,000) would be $400.
