File app and attachment default behavior


I test your great erpnext software again, and I experienced the following:

I just uploaded a file and attached to an Emplyeed document. Then I went to for ex: a task and I attached the same file, but I picked from already uploaded files, so I did not upload again from my computer.

And then I checked what happened in File app, and I see duplicated files, instead of reuse/attach the same file to both erpnext document.

Is this a default behavior? Does it excpected or did I something wrong? I am asking, bc I think there should be only one file.

Thank you for your thoughts.

update: I just saw, the second file size is 0, and the file name and URL is the same: /files/TH0003.tif
