Dropbox: Files with the same name are overwriting existing files on Dropbox integrated folder.

If you're using as subfolder name a field that may have submitted the same value more than once, then the files will be overwritten, example: 

For example, if someones called "John Smith" submits the form once a PDF with this value will be saved in a subfolder with the same name: 

But if there is someone else submitting the form using the same name the existing files will be overwritten instead of keeping a copy of the existing file. 

My testing form: https://form.jotform.com/73025004448953 

Would be possible to somehow avoid files to be overwritten? 

This is now fixed.
