Back button should cancel when reviewing an existing loop screen row

On GoCanvas Mobile (particularly for Android - I'm not sure if iOS has the same behavior), if you open an existing loop screen entry / row to review it, it is instinctive to try using the back button to leave everything alone and go back to the previous screen... but GoCanvas Mobile thinks the user is trying to delete the row when the back button is pressed and prompts the user with:

Unable to Cancel

This item has already been added to the list, delete the item from the list to discard the item.

...

Then you have to choose OK and then you have to press Done to get back to the loop screen...  but it leaves you with an uneasy feeling like you might have changed something when all you wanted to do was review the information without changing it (or you might have just accidentally chosen that row when you meant to choose a different row).

Maybe the familiar trash can icon could be added in the top nav for the delete row option and then the back button functionality could be interpreted as "go back to the previous screen without changing anything"?
