Error when booking multiple instances at once

Hi, yes it should work as long as you're looking at Opening Instances when you do the action. The error you're describing seems like a Booking Contact Form Display bug. To get around this if you go to Structure > Bookable Calendar > Booking Contact > Manage Form Display, and just click "Save" it should fix it.

It's trying to pull all the fields on the Booking Contact form and recreate that form is a VBO interface, and if you don't have a default form it doesn't know what to do. So what I need to figure out is how to make sure people have that form setup by default instead of needing to go and save it.

Let me know if that work around fixes it, if it does then I'll look into how to stop people from running into that error.

Thank you for the information. It solved my problem
