Dspace 6.3v - Cant make upload step non mandatory

Question

I am using Dspace v 6.3 xmlui. I want to make the upload step of the submission form non mandatory. I followed the steps that the wiki stated and set the webui.submit.upload.required line to false in the local.cfg file of [dspace-src]/dspace/config, and then rebuild. After that I checked, and the change in the line was taken by the correspondent files, meaning that: The dspace.cfg of [dspace-src]/dspace/config The local.cfg of [dspace]/config, and the dspace.cfg file of the [dspace]/config, all have the requirement set to false.

But in the web application, the upload step is still mandatory, I cant skip it. When I try, it looks like this: Does anybody knows why this is happening? Thanks
