The quickest solution to this is to turn off the Calculate Shear Forces/Bending Moments option at the bottom of the Part details (assuming you are not interested in these results). However, your inertia values do look a bit unusual here... Iyy is reasonable for a 400-metre vessel (though the mass seems too small for that), while Ixx and Izz are very very large.
