I use SwiftKey keyboard 1. Create a new text note 2. Insert a checkbox (touch a button at toolbar 3. Type Hel 4. Complete Hello by touching a button with the suggested word. 5. New line (by keyboard button in bottom-right) (a checkbox at the new line is inserted automatically) 6. Type Hel 7. Complete Hello by touching a button with the suggested word. Erroneous behavior: the second checkbox is removed, there is an extra char l (small L) after the cursor (see an attached screenshot).
