Note the time of your Manicure Design is 12pm. The appointment is 2h long and 20min for the Gel Polish Removal. So book the Pedicure for the 2:30pm slot. If the slot is not available that means I have another booking and the two treamtnets cannot be done one after the other on that day.
You can find another day that works. To do that clock on the ‘Bag’ icon at the top and delete the Manicure appointment. Then start again.
If you cant find time slots which are next to each other you can book the appointments for different days. Eg the manicure on Monday and pedicure on Wednesday. If you want to make this easier, you can pay for your first booking and then book and pay for the second one.
