Error from companion, can't find component

After successfully coding the app and testing, I unsuccessfully tried adding an accelerometer function. After deleting the function, the app no longer works properly. The error keeps occurring where it can no longer find the button component. I tried renaming the component and it works in the moment, but again reverts to not working after saving and resetting.

Exactly what components are YesTwo and NoTwo?

They are buttons for the second question on the page.

After more tinkering I got the emulator to function correctly. Testing is needed for a separate device running the companion just to make sure it's working there as well.
