Problematic deformed shape in response spectrum analysis

Greetings,
I am a civil engineering student in the final year and currently I am doing my diploma thesis "Structural analysis of an 150m high skyscraper, investigation of alternative core configuration solutions".
I have set up and ran a response spectrum analysis for the seismic loads. The problem is that, as you can see from the screenshot, some of the core's joints move to the opposite direction from the whole building. Does anyone have any idea for how to resolve this issue ?
Thank you in advance.
