Cursor jumps back one bar when I press record

Hi everyone, I was working on a project and all of a sudden, when I press record, the cursor is jumping back one bar and replacing the data that was on the previous bar. I don’t have pre or post roll activated, the recording mode is set to start recording at cursor. I have been working on this project for about 6 weeks it just started doing this today. The track is Halion sonic. It’s not doing this on other tracks. I have never encountered this before. Does anyone know what’s happened ?

Have you activated the metronome count-in? It’s the simplest reason I can think of.

Yes the count-in is activated - on every project I’ve ever done. But it only started doing this today, and it only does it on one track. And I cant move my hands quick enough to record without a countin anyway.

Same problem here. Very annoying.
