How does "Combine polls" work?

🍱 Features & apps polls

Hi,
Anyone with an idea how “Combine polls” works?
I only get a screen saying "Select polls by clicking on them in the right sidebar! " but the button for the right sidebar does not do anything.
… and Yes, I do have multiple date polls open for voting!

Thank you,
kr,
Martin
