create two event types with different availabilty

Hello Calendly,

I have three events and I want to keep them separate in regards to the availability but all events are showing up on one availability.

How do I separate them?

I want to arrange two groups and one 1-1 event:

1. one for one hour with up to 4 attendees
2. one for two hours with up to four attendees
3. one for a 1-1 call for 20 minutes (the most needed)

Thank you in advance,

Sally-Anne
