Two small points here...
You have to click it two times quickly, like double clicking a mouse.
sure you are using the Bypass button and not the FX Bypass.
Here's a video I just shot showing me attempting to reset the amp block.
Hopefully it shows me making a stupid mistake and you can point me in the right direction.
Don't go back to layout first. Double click Bypass while in the block edit screen.
Also, you had the drive block selected in layout and not the amp block.
