Logic Audio Goes Out of Tune Randomly!!!

Re-asking this question because i just experienced this!

Hi

I opened up an old session to export some audio files from needed for a new project and the whole session is out of tune and time .. every track has been time flexed and pitch flexed by itself and is impossible to export any normal audio files. Most notifiable is all the vocals have been pitched up to almost an octave ?

Very strange

has any body else encountered a similar problem and or know how to fix this bug ?

Thanks for any help
