Filtering feeds in folders

Hello! I’ve been trying to filter my feeds using the AI trainer but i have a problem. Using the solotion I’m using at the moment which is putting a thumbs up on the keywords I want in each feed and then putting a thumbs down on the entire feed it will not show anything in the folder which contains multiple feeds. Is there a better way to filter the feeds so that i can view multiple filterd feeds at once or am i just messing something up?

Thankful for any help!
