Radiation pattern and solution frequency in HFSS

Hello,
This is my first post. So i simulated this antenna designed for 57 GHz and was observing the radiation pattern, and i saw in the upper right corner, in the curve info, frequency is 50Ghz. What is the meaning of this if my solution frequency is 57 Ghz. Attaching the pic.

When you are plotting the far field radiation pattern you are setting the plot frequency to 50GHz and not 57GHz. If you want to plot radiation pattern of 57GHz you should go to families and set frequency to 57GHz.

I used "Ansoft HFSS Antenna Design Kit" to design and simulate antenna. Normally, I choose which frequency I want to simulate and get the result in it at the first step.

Thank you so much. Your answer helped. One more thing, this problem happened when i used interpolating setup, in fast it was ok. Do you know whats happening?
