Recipe difficulty showing on non recipe blog post

Hello!
You helped me out a few months ago by giving me some code to stop the recipe difficulty showing on my non recipe blog posts. However it no longer seems to be working on new posts or the original ones. Please can you help?
This is the css at the moment:
}
/* Hide recipe time and difficulty on single blog /
.category-blog .recipe-time,
.category-blog .recipe-difficulty {
display: none;
}
/
Hide recipe time and difficulty on single blog */

Many thanks, Emma
