Sometimes kimono has trouble selecting pieces of data on the page - in most cases, you can use advanced mode to side step this issue. If you are trying to click on an element but the element you're trying to get isn't clickable - e.g., kimono does not pop up a yellow highlight once you click on your data but instead shows no selection or actually follows the link you wanted to extract.
To get around this, click on something that is clickable near the desired element, enter advanced mode and modify the CSS selector to get the element you were looking for. To determine correct selector, you'll often need to inspect the element using your browser's element inspector.
If you still cannot select the data, then the page format might not be supported by kimono.
