Bug when using documents edited by the application

I don't use this app, but found a bug.
Visitors to my website send me CVs to apply for job offers. Sometimes I get 0Kb CVs.
After intensive research, and after eliminating all other causes. I can tell that the bug is caused by your app.
If the user, uploads the resume in an upload field on a website but in the meantime decides to modify the content of this resume through your application, but does not save the changes, and finally submits the website form , the cv will be corrupted!
