Trouble removing Post options from Category!

Hi SI Team

I am trying to get rid of “Font Size” and "Reporting" here:

http://finalbug.net

The post “About finalBUG.net” is in the Category “final BUG FAQs”
So I go to the “final BUG FAQs” category in the back end and set appropriately but this does not seem to work!

Please advise

thanks

Paul
