Revenue Cloud problem when ordering a quote

When I try to order a quote (mark the field "ordered" as true), it shows this error:

blng.OrderItemConsumptionScheduleTrigger: execution of AfterInsert caused by: System.DmlException: Insert failed. First exception on row 0; first error: INVALID_OR_NULL_FOR_RESTRICTED_PICKLIST, Unit Of Measure: bad value for restricted picklist field

I've made the Unit of Measure picklist items all the same for the following objects: 

- Consumption Schedule

- Quote Line Consumption Schedule

- Order Product Consumption Schedule

- Subscription Consumption Schedule

Is there any other object that should have the same picklist items?
