Record doesn’t drop to next track

Hi, don’t know what I’ve done, but after laying down the click track, I click ‘record’ and, instead of automatically dropping down to another track for my instrument, it carries on recording at the end of the click track! I’ve tried it without the click and it’s the same. E.g. I lay a guitar track down, click stop. Press ‘record’ button to do a vocal and it carries on recording from where I stopped the guitar track rather than starting a new track underneath! Please help!! Thankyou.

“Shift + Record” (or “Shift + R”) to record to a new track.
