Srolling problem in image hotspots

Hello,

i have a problem with the type: Image hotspots in my wordpress page. When i click on the buttons, i can´t scroll to the end of the text, because it scrolls always automatically to the beginning. Here you can see it (under the video): https://meinsvwissen.de/zeitfenster/

I hope you can help me!

Thanks,
