Is it possible to revert to non-beta Yosemite? I signed up for Yosemite betas at https://appleseed.apple.com/sp/betaprogram/ but am having issues. 

Is there any way to go back the "standard" version of Yosemite?
On System Preferences → App Store you have an option called Your computer is set to receive pre-releases Software Update seeds, use the button Change and select Do Not Show Pre-release Updates.
