static check results

Hello all, 

Here in the static check results stable it shows that there is differences between the applied load and the reactions for Some seismic load cases. But in the output file I have not received any warning, and there is not any instabilities in the model when navigating to layouts menu. 


Can someone please help me understand the reason of such differences, and would such thing affect the results  ?
