What's Wrong?

When I modify a plan using Ctrl+G, I get stuck in the screen and cannot exit. Neither pressing Esc twice nor any other known commands work to return to normal mode.
I remain stuck in the screen. The only way to exit is to completely close the conversation, losing all context and having to start from scratch.

What Should Happen?

I should be able to exit the plan modification screen and return to the normal conversation.
