We're using the GitHub and GitLab integrations. When I navigate to the Code tab in any Software Project, I get this screen

The integrations are working for seemingly every other user in our Jira, just not for me. I'm specifically trying to get GitLab to work. No matter how many times I navigate through Connect GitLab > Get Started > Link Group, my Code tab never changes. I've uninstalled and reinstalled the GitLab integration, I've revoked and replaced all the connections on GitLab's side. Still works for all my other users, just not me. Can't see any permission issues that would be causing this.
Edit:
Similar view on the Development tab.


Clicking on "Finish setup" opens this up on the right 
Both GitLab and GitHub are fully configured already, clicking on either of them confirms this.
