Redirect URI in Google Cloud Console doesn't save

Question

I have an old OAUTH1 project with a cliend id for web application. The problem is that I can't set redirect URIs. If I update them at https://console.developers.google.com/project/myprojectid/apiui/credential everything seems to be fine. But when I press F5, all the settings are gone. It seems as if Google doesn't store my settings. I have tried it with various browsers but still didn't work.

Has anyone else encountered this problem? Help is highly appreciated.

Actually pressing Save twice don't work (at least for me).
Instead, I have to hit enter into textbox. This adds entry into the list.
And only after that clicking Save will save the changes.
