Suggesting Optional Tags button is unable to be clicked

I recently created a new ankihub deck for myself and some of my classmates to use, I am able to tag cards to be in the deck but I am unable to suggest optional tags (the button appears greyed out), and when I check if any cards have been tagged in ankihub it says there have been no cards tagged?
