Workfront Documents Tab Issue

Our team noticed that too, I have logged a support ticket on it.

I noticed that change a few weeks ago to. Never got around to finding out when or why it changed. It freaked out my project managers cause they thought their documents were deleted. 

I confirm, for me it's a clear bug, but after speaking with Support today I think it still hasn't been properly recognized.
Sharing my ticket number if someone wants to refer to it: 00407135

I now learned from support this is intended behaviour, which is really stupid for me. I listed for the product team 3 reasons why I think so, if you have others please add to the list:

1. It ruins well established practice where number indicates numbers of documents (strictly speaking) 
2. It suggests there are files, when there aren't (scenario with empty folders)
3. it suggests files are missing (multiple files in single folder)

I had also raised a support ticket and they informed me that the "product team decided to change the functionality to prioritize performance."

This change does make the number count more irrelevant and less useful. We have some teams that have folders created by means of their project templates, so now all of their projects have a document number even if there are no documents within the project.
