Ok i have found thats the problem.
After creating EDL even if you see "source is accessible" with url test button it ALWAYS display 0.0.0.0/32 same in CLI.
Even if you do CLI request system external-list show type ip name EDL_NAME it will show the erorr from previous post.
To fix it you need to have policy rule which is pointing to the EDL. If you do so, after policy push edl will display IPs inside. This is imo stupid and should be changed, unless there is some more deeper logic which i cant understand due to limitation of my small brain:)
