Issue with centre of rigidity in ETABS

[engineer_dick]

after running the model, some of the centre of rigidity are not shown. IDK why and can anyone teach me how to solve it?

Are all diaphragms defined "rigid"? ETABS will report it only for rigid diaphragms.

yes, I have defined them as "rigid" but they are still not shown
