1Password's sidebar disappears when creating items

I'm having issues with not being able to click "+ add more". When I do the expected action does not happen. However everything in the left pane with categories etc becomes blank, and the "+ add more" button or whatever element it is changes color and stays that way until I click somewhere else, then the categories and tags re-appear in the left pane and the "+ add more" button reverts to its usual color.

I just tried re-installing 1Password, the issues with the latest update is so disruptive, it's worse than whatever the team fixed.
