Creating multiple tickets for an event

Hi

I’m using the free version (6.1.3) on WP 6.0.3 and can’t figure out how to create multiple tickets per event. According to the features page, this should be possible.

I can only seem to create one ticket: https://i.postimg.cc/jq958HpN/event-manager-ticket-types.png

Any advice is appreciated. TIA
