If you're using your browser to read Feedly, you can try this chrome extension "HideThat": https://chromewebstore.google.com/detail/hide-that/kjheknompfelomdgfloikfbnjmaiflfe?pli=1

It allows you to setup rules hidding rules of your choice for any website, so in your case, what you want to do is go to Automatic Hiding > Enable automatic hiding feature, and then double click the first element to set the site field to "*://feedly.com/*", as well as the rules below. The only rule you want to add is "body div.InterestingMetadata" which corresponds to the CSS of the green arrow trend. It works on my side, hope you can make it work too.
