Plotly graph disappears when adding hover elements to html code

Does Plotly Js have issues with hovering tooltips?

I’m creating a dashboard that includes a Plotly js chart. I’ve been adding tooltips to the boxes that, on hover, will display a text box. Each tooltip uses the same exact HTML/CSS code and it was going well until I added the tooltip for the top-left box.

As soon as I added that, the chart on the bottom left went blank.

Is this a bug? How can I avoid this from happening? Thanks.
