Camera Raw can't open the standard option

Hello,

I have trouble with Camera Raw. On the right side you have all these options. However, when I close the "standard tab" and go to another tab, I can't open the standard tab anymore. I have to close Camera Raw, and open the file again to get it open. But whenever I close it again I can't open it again. 
This problem is only with the standard tab, the others I can open and close without a problem.
I installed and uninstalled it 3 times but that doesn't work either. 

It's only on 1 laptop, on my other one it works fine without trouble (both macbooks).

Sorry for my bad English but I hope someone understands and can help me.
