Cannot change the visibility settings of a forked, private project

Steps to reproduce:

• Create a new public group
• Create a new private project, projectA
• Check the Settings > Permissions Settings for projectA
  • Notice that it's possible to change the project's visibility for projectA
• Fork projectA into your own personal namespace
• Check the Settings > Permissions Settings for projectA
  • Notice that it's not possible to change the project's visibility for projectA

Hello,

I'm currently striving to make a private repository public (I see a "forbidden" icon when I roll the cursor over the drop-down menu of project visibility). Maybe this is because I forked the project from another private repository of mine, that is https://gitlab.com/lucaventurini/l3 . But also in this project I have the same problem. Also, when I listed the members of this project, I saw 0 members (not even myself, but I should be the owner). I added myself (as a master, that was the maximum level I could add) but still I cannot change the visibility of the project.

Expected behavior:

When I click on the dropdown, I should be able to see the menu and click "Public"
