Ewptx csrf lab referer header

Hello everyone, I have a problem with exercises 4 and 5 in the CSRF laboratory, when the referer header is sent, the file name does not appear, so the protection mechanism with the referer header cannot be avoided as in the video . Is it because the new versions of the browsers do not allow it or am I doing something wrong? help please !!!

I am having the same issue here. Did you manage to solve it? I also tried with chromium but remains the same.
