no zooming

Hello! Images do not scale up with zooom. Once they did but now they do not anymore. I reduced the images size but nothing happened. Maybe something retated to permalinks? I have to say that I’m a beginner with wordpress. Here I report what is written in the Edit Content of a Section of page builder with the image that does not zoom. Maybe you can find some mistake…? The problem though is not limited to one immage but to all. Can you help me please?
