code visible in service section

Hi, I installed the service section on the gps routes page. Now I was trying to finish this page Before I made the images the same measures I took a look. And as you can see in the picture, after hovering with the mouse over the image, there is some code visible. Because this is the last page I make this page like a “normal” page and I removed the service section. I hope you have a solution for this. https://drive.google.com/file/d/1jAwuCIGEKmDKADjE1B5d12HkSexNbtMv/view?usp=sharing Kind regards Hans Hagmeijer
