Idea place- SAP Community

I am probably doing something wrong - I know how to up-vote/down-vote ideas, it is the ideas list that I fail to understand:

If I don't want to up/down-vote an idea and click the big orange button, nothing happens.

Even if I display the idea details, click the button and refresh the page, it is still displayed.

I have tried this in Firefox ESR 45.4.0 and PaleMoon 26.5.0. I even allowed all possible scripts to run in my browser and I still could not get rid of this orange button.

Is this a browser-related problem or I just don't understand how it works?
