Levels not the same

Instead of arriving as a single package, individual packages were shipped. The Cyan and Magenta indicated about 2/3 and 3/4 full after loading. The yellow indicated completely full. I don't know if it is a printer problem or if the ink supplied is not the same, but if they were all XL I would think the levels should indicate the same. Since the ink and the printer are both Canon I would think that Canon is a fault.
