Hi,
Please try add more this code to Customize > Custom CSS to hide it on category widget:
\
.widget.widget_categories ul li.cat-item-46912937{ display: none; }
Also, I see your first posts is too long, you should make it shorter by do following one in two ways here:
1/ Go to Customize > Standard & Classic Layout Options > and check to "Auto Render Excerpt"
2/ Add more "Continue reading" button like on this image.
Best Regards,
