Hfss 2025 R2 student calculates radiation efficiency above 100%, how to solve this problem without exceeding the mesh size allowed by the software?

I simulated a CDRA, but when I generate the radiation efficiency results the value is greater than 100%. Is there any way to get around this problem with HFSS 2025 R2 Student?
