I checked your account and job feed and can confirm that everything is working as designed. The results on your job feed are based on the search results that you`ve saved.
I`ve checked the categories you`ve picked to save and the time frames of the last job that was posted in each category are correct with your job feed.
You can also review, delete and save your search results again if you would like. If you have any additional questions let me know. Thank you.
