Page title background on specific pages not overriding global page title bg

Since the update, I can’t seem to get the page bg on specific pages to change when in the past this wasn’t an issue (when i had cb2 and metabox plugins installed). I have a default global page title bg that I want to remain for basic pages, but alter specific ones but now I can’t. How come? Even when I try to modify the settings, the setting goes back to no image chosen and the settings aren’t being saved even though the content gets update. I this is bug? Has anyone else experienced this?
