Draft Revenue Lines not being picked up in invoice generation

We have an expenditure item id that has been resubmitted for costing / revenue more than once.  Every time we do so,  when we generate revenue, the pa_draft_invoice_items table gets populated with a $0 Net zero adjustment line item line when the there should be a revenue amount.

The EI is labor, Billable, not on billing hold, cost distributed, revenue distributed and invoiced.

In EI, the Bill Amount shows 0, Bill Trans Amount shows 1080, the sum of revenue for this ei is 1080.

Puzzled!
