Sample Editor Inspector settings missing tools!!

Hi everyone, i’m shocked because i have eliminated all the tools in the Inspector side bar in the Sample Editor window and now i can’t go to the settings anymore to activate again those tools.
Is there another way to open the Inspector Settings? right click on one button of a tool doesnt work when there is NO button tool!
this is a bug?

Do you mean the tabs? all of them, even the ‘Basics’ tab (the one that contains the vol, pan and track delay?)
