Problem of resize inside a tab

Hi there

 

I'm using H5P various different items on my site. There is a problem when I put H5P items inside a tab - they resize and add a lot of space  https://studylegalenglish.com/episode-80-vocabulary-2/ You can see the difference between teh items in and outside tabs here on this page. Is anyone able to advise how to stop the adding of space inside tabs? 

 

Thanks
