Hi
I've tested version 1.5.0 and there are two issues left:
1 If I create object template named "Boats"
I can see it in table "booking_template_value"
But if that template is deleted in Booking admin, it still remains in "booking_template_value" table
2. In template list in Booking admin, if one template is selected and deleted by using Trash button,
all Properties of deleted template remains undeleted. I can see them in "booking_template_value" table,
with that Template name remaining as well.
It's not very likely that users will create and delete templates on daily basis,
but I just wanted for you to know this.
Thanks for fixing other issues :)
