It's a knows issue with CM11, ask how to fix it to the OP of the Rom which you installed or look in XDA.
You can also do a Factory Reset, which in this case I think will not help much but give it a shot, Reinstall Rom or switch to different KK Rom which do not have this issues like the Stock NUT pre-rooted one.
