There's a reason why it's a beta and not the final build. You can expect these bugs in the beta to be fixed by the time it's ready to release. If you are a developer..report it to Apple so they know..just like you should be doing for any bugs you find instead of whining about it. That is the whole point of a beta is to find all the bugs and glitches..that's why they put in the release notes that it should be used for a test device instead of your every day device..
