Dear Cecilia,
We are sorry to say that those are not a problem. It’s our plugin features and our plugin works like that.
1) The time will choose by a user when ordering, it’s your selected time slot based on your business hours. The time slot divides your business hours. The user will choose the available time slot when ordering. If your time slot is full of order for a time then no one will able to order by selecting that time slot.
2) If a customer wants to schedule the delivery for a later day, the customer will get all of your time slots based on your business hours. If your time slot is full of order for a time then no one will able to order by selecting that time slot.
If you are looking for some customized features based on your specific needs and requirements then please contact here https://www.themelooks.com/contact/ with your requirements with details to get a quote for the customization services.
