TPS62933: Regarding capacitor DC bias of WEBENCH reference circuit

Part Number: TPS62933

My name is Oda. I have a question regarding the WEBENCH results for TPS62933.

When running WEBENCH with Vin=24V, Vout=12V, and Iout=0.4A, the recommended value of the output capacitor is 47uF. Looking at the "BILL OF MATERIALS" tab, the component is "GRM32ER61C476KE15L", and this DC bias is -77.5% at 12V, and the actual capacitance is about 10.6uF. Do I have to use a regular capacitance that takes DC bias into consideration (for example, 10uF in parallel to make 47uF including DC bias)? Please confirm.
