Editing in AnkiDroid - overwhelmed with code

[A B]

Hi all,
Please see the attached photo.

Whenever I press EDIT on ankidroid, all the code shows up, making editing a very difficult task.

On my AnkiDesktop and iPad anki, this does not occur.

Would anyone be able to suggest a solution, if one exists. 

Thank you.
