When anchoring to concrete for seismic conditions, why does design fail even without seismic loads?

Please see attached design file. I am doing a design for seismic category D. I have added all the load combinations and added the loads to those combinations. In order to design for seismic loads, we need to multiply the seismic loads by a "omega" overstrength factor which I have already done. Under "loads/ calculations type" > "load type", I have selected the option to use omega factor for seismic tension and seismic shear.

Why does the design fail if I make my earthquake load equal to zero? the omega factor should only be applied to the earthquake factor. When I put "none" for seismic tension and seismic shear, then the design starts to work again. This does not make sense to me. Please provide an explanation or design example of why this is happening. Thank you!
