We dont know yet what is the 3rd panel reward, since it's bugged. If you click on the 2nd panel before going to the 3rd, it shows the UR reward, but if you go to the 1st before directly going to the 3rd, it shows the SSR reward. And if you click on the case, it shows nothing, unlike the actual SSR/UR reward on the 1st/2nd panel.

And please, dont say 3 UR/7SSR is not surprising, it is obviously not.
