Hi Ray,
I was having the same issue with my Samsung Galaxy Note 5. I had installed Google Keyboard and was using that with OneNote (instead of the default Samsung Keyboard). When I switched my keyboard back to the default Samsung Keyboard the text would delete correctly. If you aren't on a Samsung device perhaps try installing a different keyboard than the Google Keyboard (eg. Swift, Fleksy etc).
I hope that helps!
