If you’re here, you’re probably wondering why the quantities of some of your products are doubling or increasing somehow on your amendments. In addition, your bundle structure might be getting trashed. Here’s one reason why this might be happening.
There is a field on the Contract that isn’t often used called “Combine Subscription Quantities”. This functionality will combine subscription quantities but it can not be used with preserve bundle structure. So it is both combining quantities and also messing up the bundle structure when amending.
You either have to remove the use of this Contract field and set Preserve Bundle Structure to True, OR separate your products so they’re not combined and also remove/move anything you want to keep on amendments from the bundle parent to options.
