My Category's Feed at Feedburner Are Not Updating

Hello There,
My website is https://www.techgyd.com. I have created its 4 feeds at feedburner:
1. Main (TechGYD.COM Updates)
https://www.techgyd.com/feed to https://feeds.feedburner.com/TechGYD
2. TG Fun Stuff
https://www.techgyd.com/category/fun/feed to https://feeds.feedburner.com/TG-Fun
3. TG Geeky Zone
https://www.techgyd.com/category/how-to-do/feed to https://feeds.feedburner.com/TG-Geeks
4. TG Tools
https://www.techgyd.com/category/tools/feed to https://feeds.feedburner.com/TG-Tools

Although, I am keep on adding articles at every category but I found that my website’s feeds are getting updated at /category/category-slug/feed but the changes are not reflecting at Feedburner’s feed (TG Fun Stuff, TG Geeks & TG Tools) while TechGYD.COM Updates feed is updating at both end whenever articles added on my website.

I want all the other feeds will too update themselves (at Feedburner) whenever any article added to them.

Please help me to resolve this issue. Thanks in Advance.
