It seems to be an authorisation or a graphical issue, are you the project owner of the project?
However I tried to "replicate" the issue and I visualise the very same message, but it let me modify the authorised networks, therefore it could be merely a graphical issue. (I am the project owner)
I have checked with different projects facing the very same problem therefore I raised a public issue and I will push an inspection.
You can star and follow the public issue in order to get the updates.
UPDATE
The issue has been solved and the fixed rolled out.
