Default Rooted Nexus 7 won't Manually enter Recovery?

Hello,

I just unlocked and rooted my N7 using Wugfreshs toolkit. The operation seemed to go smooth, however I couldn't get it to boot into TWRP unless I used Quickboot from the system menu.

I used Wugfresh to revert it back to stock and locked the bootloader again. This time the key presses worked but rather than the stock recovery I am left with the Belly-up android with the red triangle..

What's happened to my stock recovery?
