I have tried exactly the same what you describe. I cannot reproduce it. I needed to change the background color under the tab Colors instead of Highlighting Text Styles. However if the colors are set and kate is exited, after reloading the file it shows the same colors as set.
I am using gutsy with the newest upgrades. My KDE Version is 3.5.8 and Kate Version is 2.5.8. DO you have other versions?
