[Sorted] Tuplets

Normally, when I enter tuplets, I stop them continuing by pressing :

I somehow seem to have entered a mode where I no longer have to enter : - the tuplets stop once they’re full. If I want the sequence of tuplets to continue I have to start it again over again. How can I revert to the regular behaviour and any ideas as to what I did to engage this mode (so I’ll know not to do it again)



I saved the file, closed Dorico, restarted and it wasn’t doing it anymore.
