Once the obstruction that's giving the stool an abnormal "chalky" color is relieved, the stool color will return to normal.

The direct answer to your question is that the bile isn't flowing into the gut as it normally should. The origin of the elevated conjugated bilirubin is liver obstruction cholestasis which gets put into the blood circulation and excreted through the urine. The  conjugated direct bilirubin is water soluble and thus it is passed into the urine.

The clue is chalky gray or white stool coupled with a dark yellow urine is indicative of cholestasis common for hepatitis etc.
