This is happening because of the negative margin you applied on the icon, please remove the negative margin.
That is normal in terms of CSS because now that image is behind a container
<div> on the builder, so you can't click it.
Make your Grid a 3 Columns, 2 Rows and separate the image from the icon/text. Then follow the Overlapping technique on the video above.
Or you can use the standard Row/Columns layout instead since that section design is not that complicated.
