DDJ-1000. sync button issues

Hi all,

I've never used the sync button at all as i am an ex-Vivly DJ started in 1995.

Today i accidently pressed it, and for some reason it's not doing what it's supposed to do, i've got the master track playing at just say 160.85 BPM, But when i press the sync button on the 2nd deck, it's auto syncing to 135.17BPM and not to the master track. Although i don't use it, i like to know that everything works as it should.

Thanks for reading :)
